GENERAL
The HQ488 shaver can be recharged in 1 hour
by means of a ’Fly Back Self Oscillating Power
supply’.
This electronic circuit enables the cell to be
charged at 100-240 V, 50/60 Hz.
It is possible to have a shave directly from the
mains.
The green LED only illuminates when the shaver
is connected to the mains.
The electronic circuit incorporates the following
functions and controls:
- a 1200 mA Quick Charge supply.
- a 35 mA Trickle Charge supply.
- a 1.25 V / 2.1 A Dynamic supply when shaving
from the mains.
- an open cell protection (Vbat >1.8V).
- a temperature protection of the cell.
(if Tcell - Tamb >7C, charging will switch-over
from Quick Charge to Trickle Charge).
HINTS FOR REPAIRS
- Remove the shaving unit, to prevent damages
during repairs.
- While assembling the shaver the sides panels
(item 17) have to be removed.
The side panels must be snapped into the body last.
