Note:
The HT870, when turned off, may be left on the quick charger
indefinitely without harm to the battery pack.
The HT870 may be operated both in the receive and transmit modes while being
charged in the Desktop quick charger/stand; however, the battery charging rate
drops back to the standard rate (17 hours) because a portion of the charging
current is used to power the radio.
10.3
BATTERY PACK INSTALLATION
To remove the Battery Pack, depress the Battery Lock button and slide it off
in the direction of the Lock Button. To install it, slide the Battery Pack
onto the bottom of the unit, ensuring the lock button clicks up.
CAUTION:
Never store an HT870 with the NiCad battery pack connected.
There is internal circuitry that is always connected to the
battery bus that draws a small amount of current
(microamperes) which will deplete that battery's charge
within 3 weeks. Always store the HT870 with the battery
disconnected.
10.4
QUICK CHANGING THE BATTERY PACK TO PRESERVE MEMORY
If a battery pack that needs recharging is being replaced by a second fully
charged pack, the exchange must be completed within 30 seconds. Failure to do
so will result in the erasure of all operator selected frequencies stored in
memory (m0 to m9). Always turn the HT870's power switch OFF before installing
or removing a battery pack.
10.5 OPTIONAL ALKALINE BATTERY PACK
An optional nonrechargeable alkaline battery pack is available for the HT870
(see Section 5.3). This battery pack is an ideal choice for an emergency
back-up power source as it has a storage life of approximately 2 years. The
service life of the battery pack is approximately 20 hours when operating the
HT870 in the receive mode. Alkaline batteries may be changed within this
pack.
CAUTION:
1. DO NOT try to recharge the alkaline battery.
2.
Never store an HT870 with the battery pack connected.
There is internal circuitry that is always connected
directly to the battery bus that draws a small amount
of current (microamperes) which will deplete the
battery over time. Always store the HT870 with the
battery disconnected. When batteries are changed with
a pack observe polarity.
