Charging Spare Batteries
See Chapter 6, Accessories for information on using accessories to change spare batteries.
Charging Temperature
Charge batteries in temperatures from 0°C to 45°C (32°F to 113°F). Charging is intelligently controlled by the
FR6074.
To accomplish this, for small periods of time, the FR6074 or accessory alternately enables and disables battery
charging to keep the battery at acceptable temperatures. The FR6074 or accessory indicates when charging is
disabled due to abnormal temperatures via its LED. See Table 1-2.
Powering On the FR6074
Press the Power button to turn on the FR6074. If the FR6074 does not power on perform a warm boot. See Resetting
