8.3.1 Transmit Power
The TX output power of the HX890 is set to high level (6 W (5 W)*) in factory
default, and the “ HI ” indicator is displayed at the top of the screen.
To switch the TX output power:
1. Press [
◄ ]/[ ► ] key repeatedly until the [ TX
PWR
] soft key is displayed at the bottom of
the screen.
2. Press the [ TX PWR ] soft key to switch
between “ HI ” (6 W (5 W)*), “ MD ” (2W), or
“ LO ” (1 W) output power.
*(5 W TX required in Some Countries)
NOTE
• When the SBT-13 Alkaline Battery Case is used, only the low power
(1 W) can be set.
• When the remaining power of the SBR-13LI Battery Pack is low, the
HX890 may transmit with the medium or low power, even though the
“ HI ” indicator is displayed.
8.4 TRANSMIT TIME-OUT TIMER (TOT)
When the PTT button is held down, transmit time is limited to 5 minutes. This
limits unintentional transmissions due to a stuck microphone. About 10 seconds
before automatic transmitter shutdown, a warning beep will be heard from the
speaker(s). The transceiver will automatically go to receive mode, even if the
PTT button is continually held down. Before transmitting again, the PTT button
must first be released and then pressed again.
NOTE
Once the transmitter is shut down by the TOT, transmission to the last
channel is only allowed 10 seconds after the shutdown.
8.5 SIMPLEX / DUPLEX CHANNEL USE
Refer to the VHF MARINE CHANNEL CHART (Page 98) for instructions on
use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA),
Industry Canada (Canada), and International regulations. Mode of
operation cannot be altered from simplex to duplex or vice-versa.
