Service manual

Colorado Time Systems’ battery operated scoreboards and clocks are
designed to operate 6 to 8 hours with a fully charged battery and moderate
use of the PA system. Due to individual operating habits, environmental
conditions and condition of the battery, this time may be lengthened or
shortened considerably.
CONSTANT USE OF THE PA AND SPORTS TUNES CIRCUITS WILL
REDUCE THE AVAILABLE BATTERY POWER FASTER THAN
WOULD OCCUR WITH MODERATE USE OF ALL SYSTEM
FUNCTIONS.
Each time you use your battery system, you should give it the chance to
recharge fully. Never allow the battery to completely discharge or perma-
nent, irreparable damage may result. The best method to ensure the bat-
tery power when you need it is to start a recharging cycle immediately
after using the system. Plug the 115 VAC power cord into a standard wall
outlet. The battery ON/OFF switch should be placed into the OFF position
during recharging. The battery should recharge fully during a 12-hour
period. Circuits in the system prevent over-charging the battery so that
the scoreboard can be left in a charging cycle indefinitely. After using the
scoreboard battery power, plug the unit into an electrical outlet overnight
to be sure the battery recharges fully.
The life expectancy of the internal gel-cell battery is three years. Life
expectancy is drastically affected by the care provided. Should it be
necessary to install a battery in your scoreboard, see page 7-13 of this
manual for instructions.
If you have purchased an optional external battery pack, Model BP-3
(replaces Model BP-1) for your scoreboard system, observe the following.
When your scoreboard is powered by battery only (i.e. 115 VAC wall plug
is not connected), you must observe the position of the ON/OFF switch
located on the control board. Refer to Fig. 31 or 32 on page 5-3. This
switch disconnects all battery power from the scoreboard system when it is
in the OFF position. When not using your scoreboard, you should always
leave this switch in the OFF position. Unplugging the external battery
cable from the scoreboard will serve the same purpose. If left in the ON
position, the circuits in the scoreboard will continue to drain power from
the battery and will deplete the power supply.
Your external battery pack, Model BP-3 (replaces Model BP-1) was
shipped with a 10-foot battery extension cord. This cord allows you to con-
nect power to your scoreboard even if it is mounted high off the ground.
To connect the power cord, route the extension cord through the rear
panel cover and plug the connector into one of the two receptacles desig-
nated for batteries. Refer to Fig. 31 or 32 on page 5-3. You can use either
one of the two receptacles. We suggest that you locate the mating end of
the cable where it will be accessible from the ground. Anchor the cable
along its complete run (e.g., down the pole leg for a pole mount system).
