General

Do not allow this unit to be exposed to water, steam or sand. Do not leave

the unit where excessive heat could cause damage such as in a parked car

where the heat from the sun can build up even though the outside

temperature may not seem too high. It is recommended that the F band

be used were ever possible as better results in terms of quality and freedom

from interference will usually be obtained than on the W or LW bands.

Mains adaptor

Plug the adaptor into a 13A mains outlet. Plug the lead from the adaptor into

the DC socket (22). The battery will be automatically disconnected.

The mains adaptor should be disconnected from the mains supply when not

in use.

Batteries

Remove the battery cover on the base by releasing the catches and lifting

the cover up and out. Insert six IEC R14 (C size) cells into the compartment.

Replace the battery cover.

The radio switching off and the low battery indicator (d) showing in the

display are all signs that the batteries need replacing. Battery replacement

should be carried out within 2 minutes otherwise clock/memory settings will

be lost.

In order to maintain the clock and memory functions it is important that

batteries are fitted at all times.

We would recommend for economy, that the R737 is used via the

Mains adaptor whenever possible with battery operation for occa-

sional or stand-by use only.

Aerials

On F fully extend the telescopic aerial (13), angle and rotate for best

reception.

On W and LW stations are received on the built in ferrite rod aerial, rotate

the entire radio to the position giving best reception.

The telescopic aerial is inoperative on W and LW.

Headphones

A 3.5mm socket (1) is provided for use with either stereo headphones or an

earpiece. Inserting a plug into this socket automatically mutes the internal

loudspeaker.
