Charging Cycle

4 Charging

Important!	• Rechargeable batteries (those included or those you may buy later) are deli-
	vered uncharged or partially charged. Therefore, you will need to charge each
	new battery before using it.

	Each charging slot features a tricolor STATUS LED that indicates the current operating sta-
	tus of the respective charging slot (">…<" marks an LED flashing in the respective color):

Table 1: STATUS LED indications

STATUS LED	Status

---The charger is ready to operate, no transmitter is inserted in the charging slot.

orange	The battery inside the inserted transmitter is being checked.
red	The battery is being charged.

green	The battery is fully charged; the charging cycle is com-
	pleted.

>red<	Error.

	1.	Check that a rechargeable battery is inside the transmitter battery compartment.
		Do not try to charge a dry battery.
		If there is no battery inside the battery compartment, do not place the transmitter in a
		charging slot before you inserted a rechargeable battery into the transmitter.
	2.	Make sure to switch the transmitter OFF before placing it in a charging slot.
Refer to fig. 2.		This is the only way to guarantee optimum charging.
Refer to fig. 2.	3.	Insert the transmitter into the charging slot so that the display on the transmitter faces
		the LEDs on the charger. The charger will automatically power the transmitter via the
		charging contacts.
	4.	Never switch the transmitter ON during the charging cycle. This may cause the
		charger to falsely indicate a completed charging cycle before charging is actu-
		ally completed.

Note:		If the transmitter has been switched ON by accident during the charging cycle,
		1. Remove the transmitter from the charger.
		2. Switch the transmitter OFF.
		3. Insert the transmitter into the charger.

Table 2: Charging cycle

The charging cycle will start automatically as soon as you insert a transmitter with a rechargeable battery into the charger.

STATUS LED	Status

orange	The voltage and temperature of the battery are being
	checked.

red	The battery is being charged.
	Charging time is approx. 1.5 hours for a completely dis-
	charged battery and proportionately less for a partially
	discharged battery.
	Charging two batteries simultaneously will extend the
	charging time to 3 to 4 hours.

green	The battery is fully charged; the charging cycle is com-
	pleted. The charger has switched to trickle charging mode.
	You may remove the transmitter from the charger.
	Due to the charging process, the battery may heat up to
	+60°C. This is normal.
