Master clocks are available from:
ESE
142 Sierra St.
El Segundo, CA 90245.
Telephone: 310.322.2136

To install the backup batteries:
1
Remove the blank panels in front of the Out-
put modules using the supplied hex driver.
2
Install the batteries into the battery clip,
observing the correct polarity as marked on
the battery clip and shown below.
Note:
Replace the batteries yearly to ensure con-
tinuous backup protection. Use only Panasonic P-
50AAH or equivalent batteries designed for con-
tinuous slow charge operation. To prolong battery
life, remove the batteries when the console is pow-
ered down for an extended period.
SETTING THE CLOCK
The digital time-of-day clock (not available on
the BMX
digital-14) can operate in autonomous
or slave modes. When used autonomously (the fac-
tory preset), a temperature-controlled quartz crys-
tal oscillator controls the clock timing. In slave
mode, clock timing comes from a TC89- or TC90-
compatible ESE master clock reference signal.

The operating mode (autonomous or ESE slave),
the type of ESE signal (TC89 or TC90), and the
type of clock time desired (12-hour or 24-hour
format) are set using DIP switch DS1 on the clock
PCA. DS1 is on the right rear edge of the circuit
board.
To access the clock PCA, open the meter panel.
The clock PCA is mounted behind the clock dis-
play on the meter panel.
With the clock set to autonomous mode, it must
be set after power-up. There are three clock set
buttons on the bottom left front of the clock PCA.
• Use the right button (Fast) to scroll by min-
utes at a time.
• Use the middle button (Slow) to scroll by
seconds at a time.
• Use the left button (Hold) to synchronize
the console clock to an external time refer-
ence by setting the clock ahead of the ex-
ternal time reference, then press and hold
