Entel RP520 [10/13] Feature operation

RP500

Feature Operation

12V Operation

There are 2 methods to operate your base station from 12VDC.

External back-up battery

Using the optional RP5DCL lead, an external 12V lead acid back-up battery can be

connected. The base station will float charge the battery whilst powered from a mains source.

The maximum charge current the base will deliver is 3A.

Internal Lithium Ion battery option

A dealer fit 3.6AH lithium Ion rechargeable battery can be fitted. Whilst powered from the mains,

the base station will charge the internal battery.

Mains Failure / 12V Operation Warning

If an optional mains failure back-up battery is fitted or if base is only powered from 12V battery

then a low level pip tone will sound on all transmissions to alert users that the base station is

not mains powered. (This feature is dealer programmable and can be disabled).

Talk Through & Local Control

The base station has a front mounted talk through on/off button. When talk through is on, this

will allow users to communicate using the base as a relay. Turning talk through off will prevent

users talking to each other and will only allow communication to the base. Using an optional

microphone allows the base to be used as an additional radio.

Cooling Fan

The rear mounted cooling fan has 3 dealer configurable operating modes.

1 Fan operates continuous while base is switched on

2 Fan operates only when base is transmitting

3 Fan disabled.

Transmit Tail & Pip Tones

When used in talk through, the base station has an adjustable transmit tail length, dealer

adjustable between 3-46 seconds. The transmit tail will keep the base station on transmit for the

pre-set time after a radio user has ended their transmission. To indicate the transmit tail to all

users on the radio system the base will generate pip tones for the duration of the transmit tail. If

you transmit during the transmit tail, the pip tones will stop and your transmission will be heard.

Dual Receiver

Your base station is fitted with two receivers. Where country licensing dictates, the second

receiver will be used to monitor for transmissions on the base stations transmit channel.

If a signal is detected on this channel the base will be prevented from transmitting. The second

receiver cannot be used to monitor transmissions, it is used only to lock out the transmitter

function.
