4.8 Transmitter battery voltage display
The voltage of the transmitter battery
is displayed in Volts on the large LCD
screen.
In the example shown the voltage of
the transmitter battery is 10.3 V.
4.9 Low battery voltage alarm
As soon as the battery voltage falls to a certain pre-set value,visual
and audible alarms are triggered to alert you to an impending flat
transmitter battery.
The battery symbol on the screen
flashes, and the beeper sounds.The
trigger threshold for the battery
alarm can be set to any value in the
range 8.5 - 9.6 V in increments of 0.1 V.

4.10 Charging the transmitter battery
The battery should be charged for 24 hours at a rate of 1/10 its
nominal capacity before the transmitter is used.
After use,and after any long period of storage, all the RC system
batteries should be given a charge lasting at least 14 hours at the
1/10 rate (slow charge rate), regardless of the length of the prece-
ding usage.The slow charge compensates for the batteries’self-
discharge characteristic,and balances the cells’state of charge.
(Example: 750 mAh battery: standard charge current = approx.75
mA)
The self-discharge rate of NC cells is around 1% per day.This means
that after 100 days a previously fully charged battery will be com-
pletely discharged, without ever having supplied current to any
load.
NiMH cells have the same self-discharge characteristic,but at a hig-
her rate of around 2-3% per day; the pack will be completely flat
after about 35-50 days.
The transmitter battery can be charged and discharged without
removing it from the case.
The charge socket is located next to the On/Off switch in the right-
hand side panel.
If you wish to charge the transmitter or receiver batteries at a hig-
her current than the 1/10 rate,be sure to use an automatic charger
with a "Delta-Peak" termination system.
We recommend the following battery chargers:
1.For simple charging,e.g.Lader 5,No.8308
10
Connecting the option modules to the circuit board
1. Connector for channel switches and linear sliders,chan-
nels 5 to 8
2. Connector for 8 external mixer switches
3. Trainer switch socket
4. Connector for mix trimmers; if 2 mix trimmers are to be
installed,the power supply cable for the second module
is plugged into the first module.
