TWIN TAIL CHARGER
Part no. FMG520
The fmGenie twin tail charger allows you to charge
both the transmitter & receiver at the same time.
To charge, plug the charger into the ‘chg’ socket on
the side of the fmGenies and turn on the mains
socket.
Once connected your fmGenie will safely control the charge sequence. The
recharge time is approximately 10 hours for a full charge and 4 hours for a
top up charge. The fmGenie may be used whilst charging if wished.
It is not a problem if the recharge period is
interrupted by a power failure as charging will
continue when power is restored.
If charging is not required then the fmGenie will
show “
no
” with a flashing alert indicator and
battery symbol – nothing will be happening but
unplug the charger as soon as is convenient.
You may give the fmGenie a partial charge
– you will need to clear the display with the star
button when you stop charging. Please note that
the display will be over optimistic about the
battery charge state.
Appendix 4 explains fmGenie error messages.
WARNING Only use the correct fmGenie twin tail
charger to maintain safe operation. Other types
of charger may plug in but will damage your
fmGenie.
BATTERY STATUS
The right side of the status display is a battery level indicator.
4 bars

‘no’ will be displayed if charging is attempted.
3 bars
Good battery state – a top up charge would be
permitted.
2 bars
Plan to recharge at end of day. Full charge

The audio and radio performance of the fmGenie is the same
whether the battery is fully charged or nearly flat.
0 bars, flashing battery symbol and red alert light
Low battery state with about 1 hour of use available. Recharge at the end
of the current session. When the red alert light stops flashing there should
still be about 30 mins use left.
Battery symbol only with the rest of display blank
The fmGenie has turned itself off to prevent battery damage – recharge or
replace batteries.
If charging is interrupted the number of completed charging hours will be
displayed (eg 2H). Press and hold the star button to clear the display or
re-connect the charger to continue.
Note that when the display is reset after an interrupted charge, the fmGenie will be
‘fooled’ into thinking that it has a full charge when it has not and will appear to run
down more quickly than usual.
BATTERY CHARGING
NEVER attempt to re-charge non-rechargeable batteries; they may burn
causing personal injury or damage.
