1.2 CHARGING
CAUTION
Do not change or charge batteries in a hazardous location.
Do not try to turn on or otherwise operate this instrument until it is fully charged.
Use only the MPRO-1 AC charger, the MPRO-2 220 volt AC charger, or the MPRO-6
vehicular charger. Use of any other charger may cause permanent instrument damage and
will void any warranties. The charge period is dependent on the condition of the batteries,
but should not exceed about 4 hours for a completely depleted battery pack. Partially
depleted packs will be charged in a much shorter period of time.
To commence charging with the charger supplied with AC power, connect the charger plug
to the instrument port (See Figure 1) and instrument display should read “CHARGING
BATTERY”. When charging is completed, “CHARGE COMPLETE” is displayed.
The instrument is now fully charged and ready for use.
If charging is attempted without the rechargeable battery,
or with alkaline batteries, “CHECK BATTERY” is displayed.
