16. NB/ANL/OFF SWITCH: In the ANL position, the Automatic Noise Limiter
circuit is activated. In the NB/ANL position, the RF Noise Blanker is also
activated. This Noise Blanker is very effective for repetitive impulse noise
such as ignition interference. Both ANL and NB are off when this switch is in
"OFF".
17. MODE (PA/FM/AM) SWITCH: This switch is used to select PA, FM, or
AM mode of operation. When you set to PA position, the transceiver acts as a
public address amplifier. Before operating PA, you must first connect an
external PA speaker (8 ohm, 4-watt) to the PA Speaker jack on the unit rear
panel.
18. MOD LAMP/OFF/+10KHz SWITCH: When in the MOD LAMP position,
the Mod Lamp circuit is activated. When the switch is in the +10KHz position,
the frequency is shifted up 10KHz. When this switch is in the OFF position,
the Mod Lamp does not function and the frequency is not shifted up.
19. TALKBACK/ECHO/OFF: When this switch is in the TALKBACK position,
it is used to monitor your own voice in the radio speaker. For example, you
could use this feature to compare different microphones. When in the ECHO
position, it will add an echo effect to your voice. Both Echo and Talkback are
off when this switch is in the OFF position.
20. +10KHz LED: This LED lights green when the frequency is shifted up 10KHz.
21. CHANNEL INDICATOR: Numbered LED indicates the selected channel
you wish to operate on.
22. RB/SWR LED: This LED lights red to indicate an SWR that is higher than
around 3:1. It is not an exact indicator of a 3:1 SWR. When it lights red, please
check your SWR using the built in SWR circuit. This LED lights blue to
indicate the Roger Beep circuit is on. If the Roger Beep circuit is on and the
SWR is high, during transmit both the blue and red segments of this LED will
light. The color will appear to be purple.
