M Battery charging
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
CAUTION: To avoid damage to the transceiver, turn the
power OFF while charging.
• Recommended temperature range for charging:
+10°C to +40°C (+50°F to +104°F)
• Use the specified chargers (BC-173). NEVER use another
manufacturer’s charger.
• Use the supplied AC adapter for the BC-173. NEVER use
another manufacturer’s adapters.
M Battery cautions
CAUTION! NEVER insert a battery pack or a trans-
ceiver (with the battery pack attached) that is wet or soiled
into the charger. This may result in corrosion of the charger
terminals or damage to the charger. The charger is not wa-
terproof and water can easily get into it.
NEVER incinerate used battery packs. Internal battery
gas may cause an explosion.
NEVER immerse a battery pack in water. If the battery
pack becomes wet, be sure to wipe it dry immediately (par-
ticularly the battery terminals), and especially BEFORE at-
taching it to the transceiver.
NEVER short terminals of the battery pack. Also, current
may flow into nearby metal objects, such as a necklace, etc.
Those may cause burn, electric shock or fire. Therefore, be
careful when carrying in a pocket, backpack or handbag,
and when placing the radio near metal objects.
If your battery pack seems to have no capacity even after
being charged, completely discharge it by leaving the power
ON overnight. Then, fully charge the battery pack again. If
the battery still do not retain a charge (or very little), a new
battery pack must be replaced.
Turn the transceiver OFF when charging an attached bat-
tery pack. Otherwise, the battery pack may not become
full-charging or may not charge properly.
