Installing Batteries
Setting the Battery Temperature without a BTS
NOTE: Always be aware of the temperature setting, observe the battery’s
actual temperature and adjust the Battery Temperature setting accordingly.
For varying conditions, use the Warm setting.
To configure the battery temperature:
NOTE: By default, the Battery Temp. is set to Warm.
1. Press and hold the Battery Temp. Select button for three seconds to
advance to the next setting.
2. Select the appropriate battery temperature setting.
The LEDs will indicate which of the three types is being selected:
Warm, Hot, or Cold.
NOTE: Cold is for battery temperature below 5 °C (41 °F). Warm
(default setting) is for battery temperature between 5 and 30 °C (41
and 86 °F). Hot is for battery temperature above 30 °C (86 °F). See
Table 7, “Battery Temperature Compensation Levels” on page 32 to
see how output voltage is offset by varying the temperature selection.
RISK OF BATTERY DAMAGE
Do not set a battery temperature that is lower than the actual temperature
in the absence of a BTS as this may cause the battery to be overcharged.
Similarly, do not set a battery temperature that is higher than the actual
temperature in the absence of a BTS as this may result in under-charging
the battery.
Failure to follow these instructions can damage the unit and/or
damage other equipment.
