Battery replacement
if error message received
The battery must be replaced if the error message "battery ?" is
displayed. See 7.3 “Replacing a fuse or battery" on page 97.
This message also appears if the ambient temperature around the
battery is greater than 45 °C. The battery must not be replaced in
this case. However, the ambient temperature around the battery
must be reduced, otherwise the battery life may be reduced.
Battery life To achieve satisfactory battery life, the battery temperature should
not exceed 20 °C for sustained periods of time. Higher
temperatures shorten battery life.
Please note
To guarantee battery power when needed, the batteries must be
replaced every 3 years.
Higher room temperatures (20 °C) require more frequent battery
replacements.
Switching off power supply
for longer periods
If the GMS plus will not be used for prolonged periods and the
power supply switched off, the battery module must be unplugged.
This way the battery will not be discharged, thereby extending the
battery life.
