Battery Life

Before you operate the transceiver outside, using a battery pack, it is important to
know how long the battery pack will last. The operating times listed in the table
below are measured under the following cyclic conditions:
TX: 6 seconds, RX: 6 seconds, Stand-by: 48 seconds (Battery Saver: ON)
We recommend you carry extra battery packs with you, in case the battery pack
becomes depleted.
Battery Type
KNB-63L/ KNB-65L
(7.4 V)
BT-16 (9 V)
<AAA (LR03) alkaline
batteries x 6>
Note:
◆ The high power transmission output while using the battery case (BT-16) is 3.5 W and
lower. Additionally, as is characteristic of alkaline batteries, transmission output will
decrease as time progresses. We recommend using low power when using the battery
case.
◆ Internal resistance levels differ, depending on the battery, so when using Alkaline
batteries there are times when the actual operating time may be shorter than normal.

A battery pack is in the charging slot and charging has
started.
The battery pack is defective or the battery pack
contacts are not properly mated with those of the
charger.
Charging is completed; remove the battery pack or the
transceiver from the charging slot.
The temperature of the battery pack has not satisfied
the charging start temperature. Remove the battery
pack from the charger and wait until it reaches a normal
temperature before charging it again.
