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 FM band be used were ever possible as better results in terms of quality and freedom from interference will usually be obtained than on the MW 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
Aerials
On FM fully extend the telescopic aerial (13), angle and rotate for best reception.
On MW 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 MW 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.
