2.4.3 Replacement
To replace the electronic counter, disconnect the wiring harness connector. Loosen the
plastic retaining clip and remove the meter.
Replace the meter by slotting it back into position then test as described in section 2.3.2
2.5 RAM Clearing the MPU6 meters
The MPU6 meters for short-term accountancy can be reset to zero as described in
the Machine Manual. The meters for long term accountancy and service history (alarms) can
be reset only at the factory, or by use of a special Clear down USB key as described in
section 3.3.1.3
2.6 Target payout percentage key
On UK machines the target payout percentage can be set by plugging a percentage key into
a 9-way D-type PERCENTAGE socket on the MPU6 Unit. A range of keys from 70% to 98%
payout is available and is listed in the Machine Manual, together with the associated Barcrest
Group part numbers.
2.7 Stake/jackpot key
On UK machines only, the price of play (stake) and jackpot options are set by plugging a
stake/jackpot key into a 9-way D-type STAKE/JACKPOT plug on the MPU6 unit. A range of
colour coded and labelled keys, with associated part numbers, are listed in the Machine
Manual.
2.8 Volume control
Setting of the volume control is completely controlled by software.
With the doors closed, to alter the volume, press
Hold B
while turning the REFILL key. The
Hold B
and
Hold C
buttons will now be flashing, music will be playing and the alphanumeric
display will indicate VOLUME (0-20) = n, where n is the current setting.
Pressing
Hold B
will increment the setting to increase the volume and pressing HOLD C will
decrement the setting to reduce the volume. When the desired setting has been achieved,
turning the REFILL key back to its original position will exit the volume setting routine.
2.9 Float levels
When a machine is installed it is good practice to ensure that the hoppers are full. Refer to
the relevant Machine Manual to carry out this procedure.
