General Safety & Care Information
1 General Safety & Care Information
1.1 Who Can Use This Equipment?
•Thisequipmentmustonlybeusedbypeoplesuitablytrainedintheuseofpipeandcablelocators.
1.2 Work-site Safety
• Useyourcompanies,orotherapplicablesafetycodesandruleswhenusingthisequipment.
•Unlesshavingtherequiredauthorization,licenseandappropriatetraining–DO NOT make connections to
anypipe,cableorconductor.
• DO NOTusesthisequipmentinexplosiveareas–suchasinthepresenceofflammableliquids,gases,heavydust.
• DO NOT directly connects this equipment to cables or pipes that have a potential difference to ground of
greater than 35V AC.
1.3 Equipment safety
• DO NOT open the enclosures (housings) of either the transmitter or receiver.
• Placethegroundstakefirmlyinthegroundbeforeconnectingthecablefromthetransmitter.
•DO NOT hold any uninsulated portion of the Connection leads & Clips when the transmitter is switched on.
1.4 Batteries and Environmental Safety
Vivax-Metrotech products use four types of batteries:
•Alkalinebatteries
•Ni-MH(NickelMetalHydride)–rechargeable
•Lithiumionbatteries–rechargeable
•Lithiummetalbatteries–(smallnonrechargeablebuttoncellsfor“clock”applications)
1.4.1 Alkaline Batteries
•Whenreplacingthealkalinebatteries–useonlythesizeandtypespecified–DO NOT mix battery types
(rechargeable and alkaline).
•DO NOTmixpartiallydischargedandfullychargedcellsinthesamebatterypack–DO NOT mix old with new.
•Neverattempttochargealkalinebatteries.
1.4.2 Rechargeable Batteries Nickel Metal Hydride and/or Lithium Ion
•Whenusingrechargeablebatteries,use only the correct charging device supplied or specified by the
manufacturer. The battery pack or the battery charger will contain circuitry to manage the charging process
–otherchargers(eveniftheyhavethesameconnector,polarity,voltage¤trating)willnothavethe

• Careshouldbetakenwhenchargingbatteries–NEVER repeatedly recharge batteries (or turn power off
&on)withoutusingtheinstrument.Ifusedwithaninverterinavehicle–chargetheproductthenunplug
the charger and DO NOT charge again until the rechargeable batteries have been used for at least 10
minutes. Failure to do this could result in the overcharging of the battery which will shorten the life of the
battery,andcouldinsomecircumstancescauseoverheatingorre.
• IfevertheproductbecomeshotduringthechargingprocessIMMEDIATELY unplug the charger and use
the rechargeable batteries for at least 10 minutes before recharging. If this reoccurs the next time the unit
ischarged–returnimmediatelytoVivax-Metrotechforrepair.
• LithiumIon Batteries–someproductsuseLithium ionbatteries–therequirementsformarkingand
transportation are still developing. Please contact Vivax-Metrotech before shipping products containing
