Battery Pack
The 965DSP uses a Nickel Metal Hydride (NiMH) battery
pack. Typical life of the battery pack is two years.
To change the battery pack: 1) Loosen the six screws on
the battery compartment door and remove the door.
2) Remove the old pack. 3) Unplug the battery connector.
To install a new battery pack: 1) Plug in the battery
connector. 2) Place pack in the battery compartment.
3) Replace the door and tighten the screws.
Caution: Battery may explode, leak or catch fire
if exposed to high temperatures or fire. Recycle or
dispose of properly. To prevent injuries or burns, do
not allow metal objects to contact or short circuit the
battery terminals.
Note: NiMH batteries may be recycled.
Charging
The battery pack must be charged on a regular basis.
You can typically use the 965DSP for up to 12 hours
between charges. The time between charges may be
reduced if you use the backlight frequently, use the
optional /SA or /ADSL features heavily, or if you
work in very cold weather. Charging time is 4 hours
MINIMUM. Recommended charging time is overnight
(12 hours). When the battery is charging, a charging
indicator appears when you turn on the 965DSP.
If the battery does not appear to charge fully after an
overnight charge, simply disconnect the charger, wait
a few seconds until the charging indicator disappears,
and reconnect the charger.
Level of Charge
The battery icon in the upper right of every screen
indicates the battery charge. Four black bars in the icon
indicate full charge. Zero black bars indicate the battery
pack is very low and should be charged immediately.
A warning screen appears when there are only five
minutes of charge left. Charging efficiency is best with a
temperature between 50°F (10°C) and 86° F (30°C).
Note: Do not charge the batteries at temperatures
below 32°F (0°C) or above 104° F (40°C).
