HF Desktop Charger CHH–8P
Original 26/97 Page 6
Having been charged up in the rapid charge mode, the battery is kept in full
charge using pulsed charging, i.e. switching power alternately on and off at a
variable duty cycle and a frequency of a few Hz.
The desktop charger is also provided with control logic for spare battery charg-
ing, which is allowed when no phone is connected or when the phone is in the
pulsed charge mode.
Instructions for Use
Plug in the ACS–6 AC power supply to the mains outlet. Connect the cord from
ACS–6 to the dc connector at the rear of the CHH–8 HF desktop charger.
Charging the Phone Battery
Place the phone into the recess in the charger. The right–hand indicator at the
front edge of the charger shows the charge of the phone battery. The red led is
lit during quick charging, and once the phone battery has reached full charge,
the green led alights, showing that only trickle charging is on.
When the phone is powered, the charge can be read from three indicator bars
appearing on the phone display. During the quick charging phase, each bar is lit
alternately for one second. Once the battery is fully charged all three bars are
lit. If the charger indicator is not lit when the phone is on the charger, ensure
that the phone is properly in place and that the power supply is correctly
plugged to the charger and to the wall outlet.
The battery will not accept charge if its temperature is below +5 C or above
+45 C.
Charging the Extra Battery
Place the extra battery into the recess in the charger. The left hand indicator of
the charger shows battery charge. During quick charging, the red indicator is lit
and once the battery has reached full charge, the green indicator alights show-
ing trickle charging. If the phone and the extra battery are on the charger at the
same time the phone battery is charged first, followed by charging of the extra
battery.
If the charger indicator is off when the extra battery is installed on the charger,
ensure that the extra battery is properly in place and that the power supply is
correctly plugged in to the charger and to the wall outlet.
The battery will not accept charge at a temperature of below +5 C or above
+45 C.
