the side upward and rotate the pack counterclockwise (when viewed from
the bottom). To install a pack, insert it in the socket and rotate it clock-
wise until it locks in place. A new pack must be charged before use.
Battery Operating Time
Typical operating time before recharging is required depends on
what model of transceiver you have and also how you use it. The 8560/70
models have fixed power output and the 8565 model has user-selectable
high and low power outputs. With the following times, it is also assumed
that 90% of the time is spent in the standby mode (receiving, audio
muted), 5% in the receive mode (audio enabled), and 5% in the transmit
mode. If more time is spent in the receive or transmit modes, the time
varies accordingly. Recharging is required when appears in the
display and a beep sounds when the push-to-talk switch is released. Do
not regularly use a pack until the transceiver becomes totally inoperative
because this can shorten battery life.
Transceiver 1400 mAH Battery (P.N. 587-8565-162)
8560/70 (fixed output) 14 hrs
8565 (low power selected) 10.5 hrs
8565 (high power selected) 8.5 hrs
Recharging
The battery pack can be recharged while it is attached to the trans-
ceiver or it can be removed and recharged. Charging time is somewhat
longer if the transceiver is left on while recharging, especially when using
the trickle charger. Approximate charge times with the various chargers
are shown below. It is assumed that the battery is discharged to the point
where the low-battery indication appears. When the rapid and vehicular
chargers are used, a steady or red indicator indicates charging in the rapid
mode and a flashing or green indicator indicates charging in the trickle
rate and an almost fully charged battery.
