Charging the Transmitter Batteries with the Battery Charger 

4.1  Functional Overview 

• 

Universally usable due to switching power supply technology [100-240 VAC] and primary-side 
exchangeable plug system, 

• 

Test phase at start of charging in order to ascertain the number of cells and to detect and indicate 
faulty batteries, 

• 

Short-circuit detection and electronic reversed polarity protection, 

• 

Monitoring of the charge condition during the entire charging time with a microcontroller, 

• 

Predischarging of the battery by button pressing possible; thereafter automatic switchover to 
charging, 

• 

Status display by LEDs, 

• 

Automatic switchover to pulse trickle charging. 

• 

Charging only in the temperature range +5 °C to +45 °C .

supply. 

Red ‘Charge’ LED [2]: 

Permanent light signals the charging after the contacting of the 

battery. 

Green ‘Ready’ LED [3]: 

Permanent light signals that the battery is charged. The green 

LED switches to blinking mode after approximately 2 minutes 
= pulse trickle charge. 

Yellow ‘Discharge’ LED [4]: 

Permanent light signals (after pressing of the yellow discharge 

button), the discharging. Simultaneously, the ‘Ready’ LED 
blinks for approximately 1 minute to signal the test phase. 

Discharge button [5]: 

Pressing the discharge button [for approx. 2 s] starts the 

discharging of the battery.
