Aerial Siting (continued)

Reliable operation is unlikely with a low signal strength. If the signal strength

LEDs, RSSI or FSSI readings show that the signal strength is low, you should

improve the signal strength. This may be achieved by repositioning the aerial or

fitting a higher gain aerial (CSL part number CS1053).

Where the aerial has to be installed some distance from the Dualcom a 10m

aerial extension lead is available (CSL part number CS1056).

To check the RSSI, choose one of the following options. In all cases please

have the Dualcom ESN to hand before phoning. This may be found on a label on

the Dualcom, under the battery on Dualcom Mk2 and on the end label of the

Dualcom packaging. See Fig 1 and 2.

1. Phone the automated Direct Check service on 08704 505 805 (see below).

2. Use the CS1051 Radio Test Set. See page 14.

3. Phone the Vodafone Data Network Help Desk. See page 10.

4. Phone the CSL Technical Support Desk. See page 10.

Remember: It is always easier to find the point of strongest signal before the

equipment is fitted to a wall. Moving aerials, cables, trunking etc. after installa-

tion is wasted time and effort.

VDN Direct Check

A telephone service called Direct Check is available that will tell you the RSSI

signal strength of a registered Dualcom. Direct Check is an automatic service

that you control using a telephone keypad or speech commands. All calls are

charged at the UK standard ‘b’ rate.

To use Direct Check:

1. Note the ESN of the Dualcom, See Fig 4.

2. Make sure that the aerial is assembled correctly, stationary, vertical and

that the Dualcom is powered correctly.

3. Dial Direct Check on 08700 700 600

4. Select ‘signal strength checking’ using the keypad or by speaking into the

telephone and then enter the ESN number in the same manner.

5. The signal strength will be spoken to you.
