Installation And Start-Up - Promax -4 Manual De Uso

USER'S MANUAL. PROMAX-4

Installation and start-up.

The PROMAX-4 has been designed for use as portable equipment. When the
battery is installed and the instrument is connected, the version of the instrument and
the channel plan which it has stored will appear on the display for a few moments.
When this indication appears, the instrument is in program tuning mode,
PRO:00. By means of the program RM-004, one can select the starting up of the
instrument in one of the three tuning modes: FREQ, CHAN or PROG.
When the ON/OFF key [12] is pressed, the instrument is then in "automatic cut-
off" mode; in other words, the device is automatically disconnected when twelve
minutes in operation have gone by without a key being pressed.
The automatic cut-off mode can be deactivated by holding down the ON/OFF
key for one or two seconds when the device is connected. The indicator "manual power
off" will appear on the display.
If the battery is low (at a voltage of less than 6.5 V), a blinking LOW BATTERY
message will appear on the display [3]. When the voltage is lower than 6.0 V, the
instrument disconnects.
A fully charged battery can power the equipment non-stop for more than an
hour and a half. At 30% stop/start of intermittent operation, the battery can power it for
up to five hours. When the LOW BATTERY indicator appears, the battery must be
recharged.
When a fully discharged battery is installed, it is possible that, due to residual
charges, the PROMAX-4 may start up. In this case, the instrument will automatically
disconnect before the message LOW BATTERY appears on the display.
