Charging the battery pack
Charge your PTC-860’s AFAT nickel-cadmium battery pack, if
used, before you use the unit for the first time and whenever
the battery pack becomes weak. The PTC-860’s low-battery
light glows when the battery pack is low.
Note: If you are using alkaline batteries in your PTC-860,
replace them whenever the low-battery light glows.
