Battery operation using alkaline batteries

(also see page 28)

1. Remove the battery cover on the back of the unit by sliding the cover towards
the base of the radio.

2. Slide the switch inside the battery compartment to the Alkaline position (up).
The switch is deliberately recessed to prevent accidental operation.

3. Insert four LR14 (C size) alkaline batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct polarity as
shown on the battery compartment cover. Then replace the battery cover.

• Important: when using alkaline batteries the battery switch must be
placed in the alkaline position (up). Failure to do so could result in
serious damage to the batteries or radio.

4. The low battery indicator

showing on the display, reduced power , distortion

and a ‘stuttering’ sound are all signs that the batteries may need replacing.
When the batteries have full charge the full battery indicator

will be shown

on the display.

• If the radio is not to be used for any extended period of time it is recommended
that the batteries are removed from the radio.

• We would recommend for economy that the Opus is used via the AC adaptor

whenever possible with battery operation for occasional or stand-by use
only. If extended listening using batteries is anticipated, then the use of

rechargeable batteries is recommended, see page 5.

IMPORTANT: The batteries should not be exposed to excessive heat

such as sunshine, re or the like. After use, disposable batteries should
if possible be taken to a suitable recycling centre. On no account
should batteries be disposed of by incineration.

Caution: Replace batteries only with the same or equivalent type. Danger

of explosion if the batteries are incorrectly replaced.

Battery operation using rechargeable batteries

(also see page 28)

1. Remove the battery cover on the back of the unit by sliding the cover
towards the base of the radio.

2. Slide the switch inside the battery compartment to the NiMH position
(down). The switch is deliberately recessed to prevent accidental
operation.

3. Insert four identical Rechargeable LR14 (C size) batteries into the
spaces in the compartment. Take care to ensure all batteries are
inserted with the correct polarity as shown on the battery compartment
cover. Then replace the cover. The radio is designed to be used with
Nickel Metal Hydride (NiMH) rechargeable batteries.

4. Plug the mains adaptor into your radio and then plug the adaptor into
the mains.

5. The battery indicator

will appear on the display. Part of the indicator

will ash to show that the batteries are charging. Batteries will be fully
charged in 6 - 10 hours. The battery indicator will show full and stop
ashing when the battery charging is complete.

Note: You should never attempt deliberately to recharge alkaline

batteries in the radio. Attempted recharging of alkaline batteries can
be dangerous.

• Important: when using rechargeable batteries the battery switch
must be placed in the NiMH position (down).

• When the batteries are exhausted, the low battery indicator

will show
on the screen for a short while. The radio will then switch itself off. It
may not be possible to switch the radio back on until the batteries are
recharged, or until the radio is connected to the mains adaptor.

Using the radio for the rst time

1. Place your radio on a at surface.

2. Carefully extend the telescopic aerial. The aerial should be fully
extended and positioned vertically for optimum reception.

3. Plug the mains adaptor into the DC input socket located on the rear
of your radio (marked 'DC In') ensuring that the plug is pushed fully
into the socket.

4. Plug the other end of the mains adaptor into a standard mains socket
outlet and switch on the wall socket.

5. The display on the radio will briey show a start up screen. During
this time the radio is scanning to nd a DAB radio signal. After a short

time the current time and date will appear on the display.

6. If no signal is found, it may be necessary to relocate your radio to a

position giving better reception. You should then carry out a scan to

nd stations, see 'Finding new stations' on page 8.

The AC adaptor should be disconnected from the mains supply and from
the radio when not in use.

IMPORTANT: The mains adaptor is used as the means of connecting the
product to the mains supply. The mains socket and any multi-way mains
block used for the product must remain accessible during normal use. In
order to disconnect the product from the mains, the mains adaptor should
be removed from the mains socket completely.

Use only the mains adaptor provided with the product, or a genuine
replacement provided by Roberts Radio. The use of alternative adaptors
will invalidate the guarantee.
