Channel Tuning / Frequency Tuning

Pressing key
channel tuning and back again.
In channel tuning mode turning the rotary selector [4] sequentially tunes the
channels defined in the active channels table (see the Channel set function in the TV
mode functions menu, section '4.9.4.7 Selecting the Channels Table'). When turning it
clockwise frequency increases while turning it anticlockwise frequency decreases.
In frequency tuning mode there are two ways of tuning:
1. Turning the rotary selector [4].
Turning the rotary selector [4] selects the desired frequency (tuning is
continuous from 5 to 862 MHz and from 900 to 2150 MHz). When turning it
clockwise frequency increases while turning it anticlockwise frequency
decreases.
2. Using the keyboard.
Press key [31]
frequency value in MHz using the numeric keyboard, the fifth digit and the

Automatic Transmission Search

In the TV mode, by pressing the
frequency or channel until it finds a transmission with a level higher than the search
level. The threshold level is defined by means of the Search level function of the TV
mode functions menu (see paragraph '4.9.4.16 Search Level'.).
The Search function halts the search process when the end of the present band
is reached, if it is in frequency mode, or when a key is pressed. In channel mode, the
search process is halted when the last channel of the group selected is reached (see
Appendix A). The sound is deactivated during the search process.

Selecting Analogue / Digital Mode

Measuring the characteristics of a channel depends, in the first place, on the
type of modulation: analogue or digital.
