ABOUT THE POWER SUPPLY:
The TX15 uses a sealed lead-acid 12-volt battery as its internal power
source. Unlike ni-cad batteries, this battery has no “memory” – it can
be fully recharged at any time, without damage to the battery.
When fully charged, the LED next to the power switch will illuminate
yellow with the switch in the on position. The LED will change to red
when the battery is low and needs recharging. When this happens, turn
the amp off, connect the 15-volt charger to the charger jack and plug it
in to an AC outlet. The LED near the charger jack will illuminate red
while the amp is charging and goes out when the amp is fully charged.
The battery fully recharges within 6 hours, providing at least 8 hours of
use at low levels, about 4 hours of use at moderate levels, and about 2
hours of use at continuous full power (sine wave). The battery is rated
for up to 1000 charging cycles. (The charger can also function as an AC
power supply.)
The battery inside the TX15 must be fully charged before operating the
amplifier for the first time. The amplifier leaves our factory with a
charged battery. However, the battery may lose some of its charge in
transit.
NOTE: If the battery is drained too low, the Power LED will go out. This
indicates an exhausted battery – one which may not take a charge. If
this happens, turn the amp off, connect the 15-volt charger to the
charger jack and plug it in. If the Charger LED (see #14, page 6) doesn’t
illuminate, the battery might be beyond recharging. (The TX15 uses a
“smart” charging circuit and will not allow you to charge a defective
battery.) If the battery is serviceable, the LED will illuminate once the
battery reaches 10 volts – leave the charger plugged in and let the bat-
tery fully recharge. If the LED never illuminates, the battery may need
replacing. Contact Crate’s service department:
