1. INTRODUCTION
The Personal Location Beacon (PLB) is a device used to transmit an alert in the event of an
emergency. Power is supplied by a Lithium Battery.
The Fastfind range of PLB contains these functions:
406 Hz transmitter A powerful (5 Watt) transmission encoded with
a unique serial number identifying the owner.
This signal is relayed via satellite to the
rescue centre.
The frequency of transmission is determined by the
product:
ax/G 406.037 Hz
Fastfind/Plus 406.028 Hz
121.5 Hz transmitter A low power transmission which acts as
a homing beacon.
Buzzer Audible alarm/indicator.
The Fastfind Plus and ax G PLBs also contain a GPS (Global Positioning System) receiver,
enabling it to determine its position and to include this information in the 406 Hz
transmission.
1.1. Scope
This manual provides the complete instructions issued to maintenance providers to enable
routine and emergency servicing of the PLB equipment listed below. This manual represents
the original equipment manufacturer’s (OE ) service documentation applicable to these
products.
1.2. pplicability
This manual applies to the following 406 Hz PLBs:
• c urdo Fastfind – all variants
• c urdo Fastfind Plus – all variants
• c urdo ax and ax G – all variants
NOTE: The method of distinguishing the various versions of PLB is by serial number. This is
located on the label underneath the battery pack and also in the User anual supplied with
the unit.
Serial Number Type Battery class Notes
600-XXXXXX Fastfind 1 or 2
630-XXXXXX Fastfind orse coding 1 or 2 USA only
500-XXXXXX Fastfind Plus 1 or 2 GPS
530-XXXXXX Fastfind Plus orse coding 1 or 2 USA only GPS
800-XXXXXXX Fastfind ax G 2 GPS
810-XXXXXXX Fastfind ax 2
NOTE: There are 2 variants of battery;
Class1 (-40 to +55C) or Class 2 (-20 to +55C)
W RNING: The orse-coded variants (530 and 630) cannot be converted to
standard coding, and vice versa. At this time, orse-coded variants may only be
registered in the United States.

1.3. Servicing equipment
All agents are obliged to possess specialised equipment to ensure that PLBs are serviced
correctly. A message reader (ARG5410 or equivalent) is mandatory.
Equipment:
essage reader
PLB programming kit (FPROG – c urdo P/N 85-923/924)
Thermometer (required for leak testing)
Hand tools:
Antenna rewind key ( c urdo P/N 85-753)
Flat blade torque screwdriver
Posidrive #1 torque screwdriver
NOTE: A 121.5 Hz monitor should be available (as a general surveillance instrument for all
product servicing). This will detect the homing transmission and raise an alarm if the PLB is
accidentally activated outside the screened enclosure.
1.4. Safety notices
Please read the following information for your safety:
This product has been assessed as presenting negligible hazard in a sealed serviceable
state.
Safety analysis
The following table summarises the nature of the hazard which may be present when the unit
is opened or serviced; each hazard is discussed at greater length in the detailed sections.
Hazard cause Hazard identification Precautions
Lithium battery Explosive risk, corrosive fumes,
fire, biological hazard
Handle appropriately, avoid
contact
Radio frequency
radiation
Physiological hazard Avoid close or prolonged
exposure. Do not touch the
antenna during 406 Hz
transmissions
Adhesives Skin irritation, fumes Avoid contact, ventilate well
IPA (propanol) Irritation, highly flammable Avoid contact, ventilate well

Lithium batteries
Hazardous chemicals Wear gloves
The batteries used in these products contain Lithium (Li). Lithium is inflammable, reacts
violently with water and constitutes a biological hazard. These batteries are HAZARDOUS if
short-circuited, punctured, incinerated or deformed. Lithium batteries must not be short
circuited.
Lithium batteries must be handled, transported and disposed of using appropriate safety
precautions and in accordance with applicable transportation regulations. The -20 °C battery
contains 7 grams of Lithium, the –40 °C battery contains 4.8 grams.
In the event of leakage of the battery electrolyte (which can be recognised by a pungent
odour), take care to avoid contact, particularly with open wounds; do not ingest the material.
Do not attempt to discharge a leaking battery – remove it using appropriate handling
materials and seal in a plastic bag, then dispose of it through an approved environmental
disposal agent, or in accordance with local regulations.
Radio frequency radiation
A PLB produces radio frequency radiation when it is activated. The radiated
level is below 5 W with a duty cycle of 1%. Due to the low duty cycle this is
not considered to be a hazard; however, it is advisable to avoid touching the
antenna of a transmitting PLB.
General precautions for chemical agents (adhesives, greases, IP )
Observe all safety precautions relevant to the country of operation. As a general rule,
protective overalls, gloves and goggles should be worn when handling these chemical
agents, but different countries may have additional requirements which must be observed.
Ensure that all chemical agents are handled in accordance with the manufacturer's
instructions, and that suitable protective clothing is worn.
ake sure that the working area is well ventilated, and that chemical substances are not left
exposed. Observe good hygiene practices; do not eat, drink or smoke when handling
chemicals.
Read the manufacturer's instructions before using any chemical agent.

1.5. False alarms
Every care must be taken to avoid the generation of false alarms.
For test purposes the PLB may be operated in the following ways without generating a false
alarm:
1. Self test mode (but avoid repetitive self tests)
2. Live mode for less than 120 seconds (after 120 s a live transmission is made)
3. Live mode in a screened enclosure
If for any reason the PLB is activated outside a screened enclosure (other than as a self test
and for less than 120 seconds), it must be assumed that a false alarm has been generated. It
is not sufficient to de-activate the PLB immediately – once the transmission has been made
the alert has been generated.
The rescue services must be informed immediately that there has been a false alarm. Use
any means available to contact the nearest Rescue Coordination Centre (RCC); state that
there has probably been a false alarm, identify the location of the PLB and if possible give
the PLB ID.
De-activating a live PLB
Press and hold the OFF/Test button; wait for the red LED to extinguish.
If the LED does not extinguish, remove the battery (refer to section 3.8) and return the PLB to
c urdo for investigation.

2. SSESSMENT
2.1. Maintenance tasks
Servicing agents are reminded that it is their responsibility to ensure that the procedures are
followed, that only c urdo approved parts are fitted, and that good practice is observed.
False alarms caused by inadvertent activation must be avoided. We recommend that PLB
testing is only done in self-test mode to avoid false alarms.
The functions which can be performed by servicing agents are:
• Routine testing
• Reprogramming
• essage reading and verification
• Battery replacement
• Leak testing if required
• Antenna rewind
2.2. Routine testing
Every PLB should be tested monthly by its owner to ensure functionality. Wherever possible
the PLB should also be inspected for mechanical damage.
Whatever the reason for the return of a PLB to a maintenance agent, the PLB must be
subjected to a full assessment before any other action is taken. The agent has a
responsibility to ensure the PLB is completely serviceable and is fit for its purpose.
2.3. GPS upgrade
A product improvement was implemented on the Fastfind Plus PLB. Upgraded PLBs are
easily recognized by the warning on top of the PLB. If an original Fastfind Plus is received,
every effort should be made to have the PLB upgraded – contact
customerservice@mcmurdo.co.uk for advice.
2.4. ssessment
Every PLB returned for servicing, of whatever nature, must be fully assessed to determine its
operational status.
ssessment form
The flowchart and assessment form, shown on the next pages, are essential tools in
performing diagnosis.
The assessment form (or equivalent) must accompany any warranty return to the
manufacturer, and may be used to support customer billing. The first section of the form
records the customer, the PLB and the reason for return (as 'Customer comments'). It is
essential to record the identity details from the PLB rear label, as these will be necessary for
comparison with the transmitted data. The expiry date must be noted; if less than 6 months
life remains, a battery change should be recommended to the customer. Procedures for the
rest of the form are detailed in section 3.
