Care and Maintenance
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).
