Appendix C–6
BATTERY CHARGING
The 4640-B with fully charged batteries will remain operational for
approximately 8 weeks under normal conditions.
If the batteries become discharged, the following message will be
displayed on the gauge:
<READY> mm/dd/yy
Avg: xx
Time: xx min.
BATTERY LOW!
When this display appears, there are a few hours remaining before
the battery must be recharged. For emergency use, a 30-minute
recharge with the dc or ac charger provides several hours of use.
Although batteries cannot be “overcharged,” rechargeable batteries
have a “memory” and repeated needless recharging will shorten the
battery life. If possible, run the batteries down before recharging.
NOTE
Batteries should not be recharged unless the BATTERY
LOW! indicator is visible!
ALKALINE BATTERY USE
If recharging is not an option, alkaline batteries may be installed
temporarily . Separate battery cases (PN 104148) can be purchased
as an option.
WARNING
Do not mix alkaline and rechargeable batteries in the
gauge. Charging may cause alkaline batteries to
explode!
