f. If the battery becomes hot whilst on charge, to the
point where you can no longer touch the pack, in-
terrupt the charge process immediately.
g. When the charge process is complete, first discon-
nect the transmitter / battery from the charger, and
then the charger from the power source.
h. When the charge process is complete, check the
charge quantity calculated by the battery manage-
ment circuit, and correct it if necessary (

The term "battery management" means that the trans-
mitter measures the current when the unit is in use
and when the battery is on charge. From this data the
software calculates the actual state of charge of the
battery, and displays it on-screen in Status display 4

Transmitter (
Fig. 8.4.2.).
When the RF module is operating (LED flashes red)
the expected residual operating time is calculated
and displayed in Status display 4. This indicates how
long the transmitter should be able to operate if the
current drain remains the same:

Self-discharge

When the transmitter is stored, the system also takes
into account the battery's rate of self-discharge, and
corrects the available battery charge quantity accord-
ingly.
pro
The ROYAL uses transmitter batteries of the type
PERMABATT+. The new manufacturing process used
for these batteries has reduced the rate of self-
discharge to around 0.07% per day (approx. 25% self-
discharge annually). The self-discharge rate of con-
ventional NiMH batteries is around 1.5% per day.
For this reason the menu ¡Setup, Transmitter in-
cludes the menu point SlfDsCharge (self-discharge):

In this menu point it is possible to switch the self-dis-
charge rate between "low" (approx. 25% per year)
and "normal" (approx. 1.5 % per day). The factory de-
fault setting is "low".

Battery management only provides supple-
mentary information!
Battery charge and residual time represent additional
information relating to the condition of the transmitter
battery, and are intended to provide additional security
when handling the transmitter. However, major dis-
crepancies may occur due to production tolerances,
battery ageing and the effects of battery maintenance.
In any case the system only works properly if the ca-

Unchanged features

Voltage display:
Virtually all modern transmitters display the actual bat-
tery voltage as a numerical value and / or in graphic
form (bar graph).
Battery alarm:
If the battery voltage falls below a certain minimum
value, the transmitter emits an audible alarm. On
many transmitters the alarm threshold is variable.
As you would expect, the ROYAL

This is important

To ensure that the battery management function dis-
plays values which are as close to "the truth" as pos-
sible, it is essential to observe the following points:
a. Correcting the battery capacity
The battery management function assumes that
the transmitter is fitted with a battery of 2100 mAh
capacity. When the transmitter battery has been
conditioned (more than five charge / discharge cy-
cles) you can correct any discrepancy from the
nominal capacity as follows:
Menu: LSetup, Transmitter,
Parameter: Battery Capacity.
At this point you can set the value determined by
the battery charger (in increments of 50 mAh).
!
When the battery voltage falls below 6.5 V,
the available charge quantity is set to 0 mAh.
b. Correcting the available battery charge quantity
If you fit a new transmitter battery, or charge it di-
rectly (i.e. not via the socket on the back panel),
then the available battery charge quantity must be
corrected manually:
Menu: LSetup, Transmitter,
Parameter: Battery charge.
!
If the battery voltage is above 8.6 V when
the transmitter is switched on, the battery
charge quantity is set to the value which is set
for battery capacity in the menu ¡Setup,
Transmitter.
!
If the battery voltage falls below 6.5 V, the
available charge quantity is set to 0 mAh.
