BASIC OPERATION

■ Transmitting

CAUTION: Transmitting without an antenna will damage
the transceiver.
NOTE: To prevent interference, listen on the channel be-
fore transmitting by pushing and holding [SQL].
qSet the operating frequency.
(pgs. 18, 19)
• Transmission is available on the 144
MHz/430 MHz amateur bands only.
• Select output power if desired. See
the section at right for details.
w Push and hold [PTT] to transmit.
• Tx/Rx indicator lights red.
• S/RF meter shows the output
power level.
e Speak into the microphone
using your normal voice level.
• DO NOT hold the transceiver too close to your mouth or speak
too loudly. This may distort your speech.
r Release [PTT] to return to receive.
WARNING! NEVER continuously transmit for long periods of time. When the transceiver is used for continuous prolonged
transmission at high power, the transceiver radiates heat to protect itself from overheating and transceiver's chassis will be-
come hot. This may cause a burn.
DO NOT operate the transceiver in a situation that will obstruct heat dissipation, especially if the transceiver is operated with
an external power supply. Heat dissipation may be affected, and it may cause a burn, warp the casing or damage the trans-
ceiver.
CONNECT the rated range voltage when using external power supply.
NOTE: Transmit power set 2.5 W (MID) automatically when the transceiver radiates heat.

■ Transmit power selection

The transceiver has four output power levels to suit your
operating requirements. S-Low output power during short-
range communications may reduce the possibility of interfer-
ence to other stations and will reduce current consumption.
➥ Push and hold [LOW](3) for 1 sec. to toggle the trans-
mit output power between High (5W*), Mid (2.5 W*),
Low (0.5 W*) and S-Low (0.1 W*).

ONLY S-Low power operation is
available while using BP-257.
While pushing and holding [MODE](REC),
rotate [DIAL] is also available to select
transmit power.
