Cautions:
• The power supply must be able to
deliver 12 volts and at least 1200 mil-
liamps of power. The recommended
power supply meets these specifica-
tions. Using a power supply that
does not meet these specifications
could damage the TRC-237 or the
power supply.
• You must use a DC fused cord that
supplies 12 volts and delivers at
least 1200 milliamps of power. Its
center tip must be set to positive,
and its barrel plug must correctly fit
the TRC-237’s
POWER
jack. The rec-
ommended fused cord meets these
specifications. Using a fused cord
that does not meet these specifica-
tions could damage the TRC-237 or
the fused cord.
• To help prevent an electrical short,
unplug the DC fused cord’s plug from
the AC adapter’s power socket be-
fore you unplug the cord’s barrel plug
from the TRC-237.
Follow these steps to connect the TRC-
237 to AC power.
1. If the TRC-237 is on, turn
OFF/VOL-
UME
fully counterclockwise until it
clicks to turn it off.
2. Connect the DC fused cord’s 5.5 mm
outer diameter/2.1 mm inner diame-
ter barrel plug to the TRC-237’s
POWER
jack.
3. Be sure
ALKALINE/NI

4. Plug the DC fused cord’s other end
into the power supply’s power socket.
5. Plug the power supply into a stan-
dard AC outlet, then turn on the pow-
er supply.
