1)
VOLUME CONTROL.
2)
LED INDICATION: OPEN SQUELCH (yellow Led). The Led is on when the AF output is active.
3)
DISMOUNTABLE BELT CLIP.
The clip can be removed from the apparatus by pulling aside the fastening pins.
It can be mounted on the transmitter also upside-down, to use the transmitter with downwards front-panel.
4)
AF OUTPUT CONNECTOR (Fischer D102 type, 3-pin female, for CPR 30-F version).
The AF output is balanced and referred to ground: therefore both output wires must be hold insulated from ground.
• pin 1 = ground (it must be kept not-connected); • pin 2 = AF-a output; • pin 3 = AF-b output.
On request, the CPR 30 can be supplied with 3.5 mm jack-plug (CPR 30-J version).
5)
LED INDICATION: APPARATUS-ON / LOW-BATTERY STATUS (green LED)
• the Led lights when the apparatus is on,
• the Led blinks slow when the residual battery capacity is less than 25% of the full charge,
• the Led blinks fast when the residual battery capacity is less than 12% of the full charge.
6)
ON/OFF SWITCH.
The apparatus is off when the switch is set on the “O” sign.
7)
ANTENNA CONNECTOR (Lemo coax-00 type).
8)
SELECTOR: CHANNEL GROUP ( 1 / 2 ).
9)
SELECTOR: CHANNEL ( 0 ÷ F ).
10)
PUSH BUTTONS TO OPEN THE BATTERY COVER.
11)
LED INDICATOR: BATTERY-LIFETIME (4-step LED-bar-graph: 100%, 75%, 50%, 25% ).
Under the battery compartment is placed a selector allowing to pre-set the battery-lifetime indicator either for alkaline batteries
“ALK” or Ni-MH accumulators “Ni-MH”.
WARNING: we recommend the use of high-quality alkaline batteries or rechargeable Ni-MH cells.
