Transmitting
Press the PTT (Press-to-talk) switch on the handset or microphone
to talk, and release it to listen for the response.
Output power
• BEFORE transmitting, think about the subjects which have to be commu-
nicated and, if necessary, prepare written notes to avoid unecessary inter-
ruptions and ensure that no valuable time is wasted on a busy channel.
• Listen before commencing to transmit to make certain that the channel is
not already in use.
Each press of the [HI/LOW] key selects HI or LOW output power.
The transmitter power is automatically set for low on the follow-
ing channels.
International: CH15, CH17
USA: CH13, CH15, CH17, CH67; to operate USA chan-
nel 13 or 67 in high power, keep [HI/LOW]
pressed while talking into the handset.
Turning the loudspeaker on/off
To turn the loudspeaker on/off, press the VOLUME control. The
loudspeaker off mark appears when the speaker is off. The loud-
speaker is automatically turned off when the telephone handset is
used on semi-duplex channels.
Channel 16
Press the [CH16] key to select channel CH16, International Call-
ing and Safety Channel.
This is an international calling and safety channel. The use is lim-
ited for distress, safety and calling. The transmission on CH16
(156.800 MHz) should be limited to within 1 minute except for
distress calling.
Avoid calling on Channel 16 for purposes other than distress, ur-
gency and very brief safety communications when another calling
channel is available.
