When charging is complete, remove the plug of the battery charger from the jack of
the transceiver.
Cautions
z Neither transmission nor reception can be performed while charging the battery pack using the
supplied battery charger.
z Charging may cause noise in the nearby TV or radio. Charge the battery pack with the battery
charger as far away as possible from a TV or radio.
z If "BATTERY NOT INSTALLED" appears on the LCD and the battery pack cannot be charged
after lapse of 11 or more hours, stop charging the battery pack immediately. If the same message
appears again, the battery pack is presumably at the end of its service life or defective. If so, replace
the battery pack with a new one.
z While charging the battery pack, protect the transceiver from water.
z Charge the battery pack in a place where the ambient temperature is +5 °C to +35 °C (+41 °F to
+95 °F).
z If the terminal or electrode of the battery case is dirty, this transceiver can malfunction due to poor
contact, resulting in overheating or rupture. If the terminal or electrode gets dirty, clean it using a dry
cloth or cotton swab.
Tips
• The battery charger may become hot during charging. This is not a malfunction.
• If _ starts blinking, the battery pack charge is depleted. Charge it immediately.
