Operation of the
VR-5000
initially is set up in the “ AUTO ” mode (mentioned in the previ-
ous section), whereby the reception mode (such as AM or FM) is automatically set accord-
ing to the frequency in use; at the same time, the channel steps typically used in that fre-
quency segment are also programmed automatically.
However, some frequency segments involve several different services which may use dif-
ferent channel steps. So you may wish to modify the channel steps; to do this, you must
first exit the “
AUTO
” mode, then select the desired steps. The procedure is:
1. Note the operating mode in which you are operating via the “
AUTO
” mode (for ex-
ample, FM-N).
2. Press the [ MODE
(
ADRS
)
] key as many times as required to shift to the operating
mode which had been selected by the “ AUTO ” mode.
3. Press the [ STEP
(
PLAY
)
] key as many times as required to shift to the desired channel
step selection (for example, 5 kHz).

The
VR-5000
provides two VFOs (MAIN VFO and SUB VFO), which operate in a Dual
Receive configuration (simultaneous reception using both VFOs). The SUB VFO frequency
must be set within ±20 MHz of the MAIN VFO frequency (for example, if the MAIN VFO
is set to 1280.000 MHz, the SUB VFO can be set to 1260.000 ~ 1300.000 MHz). Also, the
SUB VFO may be set only AM or FM-N modes.
The MAIN VFO is the upper displayed frequency, while the SUB VFO is the lower dis-
played frequency. The relative size of the frequency displays indicates which VFO you
currently are tuning on (the
larger display size indicates the “active” VFO). Independent
Volume controls are provided for each VFO; just turn the Volume down if you do not wish
to listen to communications on a particular channel.
