When using a BP-208 OPTIONAL BATTERY CASE attached to the
transceiver, install 6 AA (R6) size alkaline batteries as illustrated
below.

cient power in case of an emergency, etc.
D D CAUTIONS
• Use ALKALINE batteries only.
• Make sure all battery cells are the same brand, type and ca-
pacity.
• Never mix old and new batteries.
Either of the above may cause a fire hazard or damage the
transceiver, if ignored.
• Never incinerate used battery cells since internal battery gas
may cause them to rupture.

If the battery case gets wet, be sure to wipe it dry before using
it.
