Ringer Equivalence Number

There is no limit to the number of telephone sockets you can have on one
telephone line, but the number of telephones that can be connected at the
same time is limited by their Ringer Equivalence Number (REN). All approved
telephone equipment which plugs into the telephone line should have an REN
indicated on it. The phoneflash has an REN of 0.5. The total of the REN
added together should not be more than 4 otherwise the phoneflash or
other equipment might not flash or ring properly. Most equipment has a REN
of 1 so 4 pieces of telephone equipment e.g. 2 telephones, 1 phoneflash
and an answerphone (all with a REN of 1) would be the most that could be
connected at once.
The phoneflash may be connected to Direct Exchange Lines (D.E.L.), and any
Private Branch Exchange (P.A.B.X.). This apparatus must be connected in
parallel with other approved apparatus, where calls may be answered when a
ringing indication is given. It is however, not suitable as an extension to a Pay
Phone Circuit, nor should it be connected to shared service lines on the
P.S.T.N., or as part of a 1+1 carrier system.

Instructions for use

• Your phoneflash is supplied ready for use with an integral mains lead and
telephone line cord, a wall mounting bracket, screw pack and a double
telephone adaptor.
• Fit the double telephone adaptor into the telephone wall socket and plug in
the telephone and the phoneflash. Then plug the mains lead into the
mains socket and switch on.
• When an incoming call is detected it will flash in time with the ringing of
the telephone.
• The wall bracket should be fixed to the wall using screws supplied. The long
vertical part of the bracket should be placed flush against the wall with the
screw head recesses and mounting lugs away from the wall. The
phoneflash will locate over the two lugs and then should be slid
downwards to fix firmly.
