Frequency Tuning; Channel-Frequency Mode Configuration - Promax PROPOWER - 5 Mode D'emploi

USER'S MANUAL. PROPOWER-5

4.2.3.2 Frequency tuning

When in CHANNEL-FREQUENCY
operating mode, pressing the CH-FR [10]
key switches tuning by channel to tuning
by frequency and vice versa. In the tuning by
frequency mode in the case that LEVEL mode has
been selected (see section "4.2.3.3 CHANNEL-
FREQUENCY mode configuration") the instrument
becomes a receiver with a resolution of 10 kHz in the
1 to 50 MHz band. In this mode you may tune to any signal within the band, including
leakage pilots, telephone and communications signals. To change tuning simply press
the rotary selector [9] until the digit you want to change is underlined and then turn the
rotary selector [9]. The channel number will appear to the left of the tuning frequency, as
long as it corresponds to an active channel.
Remark: When switching from frequency to channel, if the tuned frequency does not
correspond to any channel, the PROPOWER-5 will search for the channel
nearest to this frequency and will stay tuned to this channel. This operation
may take a few moments.

4.2.3.3 CHANNEL-FREQUENCY mode configuration

In CHANNEL-FREQUENCY
pressing the CONFIG key [14] will access
the first page of the configuration menu of
the parameters relative to this mode.
The parameters which may be changed and their
margins are shown in the following table. To change a
given parameter turn the rotary selector [9] until the field
is activated (it will appear shadowed) and then press. The value of the parameter will be
activated and may be changed by turning the rotary selector. When the value you want
appears, press the rotary selector [9] to validate it.
