Information concerning the battery pack:
Thebatterypackincludesammableobjectssuchasorganic
solvent. Mishandling may cause the battery to rupture
producingamesorextremeheat,deteriorate,orcauseother
forms of damage to the battery. Please observe the following
prohibitive matters.
• Do not disassemble or reconstruct battery!
Thebatterypackhasasafetyfunctionandprotectioncircuitto
avoid danger. If they suffer serious damage, the battery may
generateheatorsmoke,rupture,orburstintoame.
• Do not short-circuit the battery!

• Do not incinerate or apply heat to the battery!
If the insulator is melted, the gas release vent or safety function is
damaged, or the electrolyte is ignited, the battery may generate
heatorsmoke,rupture,orburstintoame.
• Do not leave the battery near fire, stoves, or other heat
generators (areas reaching over 80°C/ 176°F)!

1 SettheChannelselectortochannel1,thenpullthe
Channel selector knob off the transceiver.
• IftheChannelselectorisnotpositionedatchannel1,theknobmay
not install correctly and the channel may be unable to change.
2Insert the channel stopper.
3 SetthearrowoftheChannelstoppertothehighestchannel

4Reinsert the Channel selector knob.
Screwtheantennaintotheconnectoronthe
top of the transceiver by holding the antenna at
its base and turning it clockwise until secure.
Note:Theantennaisneitherahandle,a
keyringretainer,noraspeaker/microphone
