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.

Bluetooth mode

Info.

The Bluetooth mode on your radio allows you to play audio, play sound from video les and stream music from Bluetooth capable devices such as

your mobile phone, computer, tablet etc. through your radio's loudspeakers.

● When a Bluetooth enabled device such as your Opus Radio is in a 'discoverable' state other Bluetooth devices can detect, pair with or connect

to it.

● 'Bluetooth pairing' occurs when two Bluetooth enabled devices agree to establish a connection and communicate with each other.

Connecting Bluetooth devices

1. Ensure that the Bluetooth capability on your phone, tablet or PC is enabled. You
may need to refer to the user documentation for your device, since the method
will vary with each device.

2. Press the On/Off button to switch on your radio. The radio will beep to conrm
that it is now switched on.

3. Press the Bluetooth button on your radio to select the Bluetooth mode. Y our radio
will show that it is 'discoverable' and 'Pairing' will show on the display. If the radio is
already connected to another device to cause the radio to become 'discoverable',
apply a long press on the Select/Info button. Y our Opus will become discoverable
by other devices and 'Not connected' will show on the display.

4. Using the Bluetooth settings of your phone, tablet or PC direct it to search for
'discoverable' devices. After a few seconds, you should see a device named 'Opus'.
Just occasionally it may take longer for the radio to be found by your device.

5. Select 'Opus' to cause your phone, tablet or PC to pair with your radio and to
establish a connection.

6. Once the connection is established 'Connected' will show on the display.

You can now begin playing music from your smart-phone, tablet, etc.

Some Bluetooth devices may require a 'Passkey' (an authentication key) in order to
establish a link between devices. A passkey is similar to a password, although you
only need to use the passkey once to establish a link. If your device asks for a passkey
to be able to pair with your radio then enter a code of 0000 (four zeroes).

Playing audio les in Bluetooth mode

Info.

When you have successfully connected your radio with your chosen Bluetooth
device you can start to play your music using the controls on the device.

1. Once playing has started adjust the volume to the required setting using
the Volume control on your radio or the connected Bluetooth device.

2. The volume of your radio in Bluetooth mode is affected by the volume
settings on the radio and also on the connected Bluetooth device.

If you adjust the volume control on the radio but you nd that the volume

from the radio is not sufcient, it may be that the volume setting of the

connected device needs to be increased.

3. The audio player in your phone, tablet or PC may be able to respond to
the Play/Pause, Next track or Previous track buttons on the radio.

Note: Not all player applications or devices may respond to all of these

buttons.

Connecting and reconnecting a Bluetooth device

Y ou can only have one Bluetooth device connected to the radio at any one time
although it may be paired with several devices. Once you have a Bluetooth
enabled device connected to your radio it cannot be interrupted by another
Bluetooth device unless you choose to break the connection.

1. To connect to a different device, apply a long press on the Select/Info
button. 'Not connected' will show on the display.

2. Your Opus radio will become discoverable by other devices.

3. You can now pair the radio with a new device using its Bluetooth settings
the radio will be listed as 'Opus'. When the new Bluetooth connection has
been established 'Connected' will show on the display. Y ou may then play
music from the new device through the radio.

4. If you no longer want your Bluetooth device to be paired with your radio
you will need to delete the 'Opus' pairing on the device. Please refer to
the device's Bluetooth documentation.

Bluetooth information

Bluetooth connectivity performance may vary depending on the connected
Bluetooth devices. Please refer to the Bluetooth capabilities of your device
before connecting to your radio. All features may not be supported on
some paired Bluetooth devices.

A Bluetooth connection can provide a link for audio up to a distance of
approximately ten metres. When pairing two Bluetooth enabled devices,
for convenience, we recommend they should be no more than 2 to 3
metres apart.The presence of other functioning Bluetooth devices during

connection may lead to operational difculties.

Bluetooth is a short-range radio communication system and generally
Bluetooth devices can communicate with each other clearly within a regular

sized room or ofce. The reliability of a Bluetooth connection between

different rooms will greatly depend upon the construction of the building.

Bluetooth communication range may be substantially reduced if the signal
passes through a solid object. Human bodies, brick and concrete walls,
heavy furniture or bookcases will all reduce the operational range of your
Bluetooth devices to a greater or lesser extent. Glass, dry-wall or wood

paneled walls and ofce partitions may have a less severe but noticeable

effect. Metal pipes, foil-lined plasterboard, metal window frames and
domestic wiring can also have an effect. Y ou should position your Bluetooth

devices closer to each other if you observe communication difculties.

WiFi networks and cordless phones generally use similar radio frequencies
to Bluetooth and may interfere with one another. If any interference is
noticed, then try relocating the radio or one of the other devices.

The Bluetooth capabilities of your radio enable it to receive audio from many
Bluetooth capable devices including mobile phones, personal computers
and tablets. Only one Bluetooth device can be connected to your radio

at a time. It supports the following Bluetooth proles and functionality.

● Your radio supports A2DP (Advanced Audio Distribution Prole) which

is a stereo audio connection that streams stereo music from PCs,
mobile phones etc. SBC and AAC audio codecs are supported.

● Your radio supports AVRCP (Audio Video Remote Control Prole)

which allows your radio to control music playback from the connected
device.

Note: Some mobile phones may temporarily disconnect from your radio
when you make or receive calls. Some devices may temporarily mute their
Bluetooth audio streaming when they receive text messages, emails or for
other reasons unrelated to audio streaming. Such behaviour is a function
of the connected device and does not indicate a fault with your radio.

If your connected device is able to provide information from the track being
played you may press the Select/Info button on the radio to display the
Title, Artist and Album details, please see page 11.

Note: If the unit is in the Bluetooth mode and it is not connected to a
Bluetooth device for more than 15 minutes it will automatically switch to
the standby mode. If powered from batteries the radio will then switch
off completely. To use the radio again, simply press the On/Off button to
switch it on.

Using USB memory devices

This section describes how to use your radio to access and playback your audio

les via USB memory devices. USB memory devices plug into the rectangular

slot on the top of the radio.
The Opus radio has been tested with a range of USB memory devices of up to

128GB capacity. USB memory must use the FAT or FAT 32 ling system in order

to operate with your radio. Your radio is unable to play from media formatted
using the exFA T or NTFS formats. Your radio is only designed to work with USB

ash memory devices. It is not intended to be connected to hard disk drives or

any other type of USB device.
It is possible to use SD, SDHC or SDXC cards for media storage and

playback when held in a suitable USB adaptor. However, due to the
wide variation of such adaptors, it is not possible to guarantee that all
adaptor / card combinations will work in the radio.

Audio formats supported are AAC, FLAC, MP3, WMA, Ogg Vorbis and WAV.

USB playback does not support les encoded using WMA Lossless, WMA
Voice, WMA 10 Professional, nor les of any format which have DRM protection.

Recommendations:

Unless you have only a few les on the USB memory device, do not place

all les in the root folder.

The number of items (les / sub-folders) in any folder should be less than

2000.

Searching and playback will be more responsive if the number of les in

any one folder is limited (we suggest not more than 250).

It is recommended that the USB memory is reformatted in your computer

before adding your music les.

The maximum depth of folder nesting permitted is 8 folder levels.

Recording to USB memory device

Your Opus radio has been designed to allow you to make recordings to USB
memory devices. Recordings are made in MP3 format at 320k bits per second.

USB memory media must use the FAT or FAT32 le system in order to operate

with the Opus radio. Such media is usually supplied already formatted or can
be formatted using a PC with a suitable USB connection.

It is also possible to record onto media which already contains les written by
the radio or your computer. The recorded les will be added to those already

present on the media.

Make a recording

1. Select the desired source for the recording (DAB, FM, Bluetooth, Auxiliary

in (also see page 22), internal MIC or external MIC (also see page 23). DAB

radio is shown in the illustration.

2. Set the volume to the required listening level (the volume of the recording
will not be affected by this).

3. Carefully insert the USB memory device on to which the recording is to be
made into the USB socket on the top of the radio.

4. Apply a long press on the Record button. The display will show 'Record
init...' and a double beep will be heard. Recording will start after a few seconds
and a second double beep will be heard. While recording is in progress the
recording source and elapsed record time will show on the display.

5. T o stop the recording press the Record button or the Stop button. Recording

will stop, a long beep will be heard and the recorded le will have been written

to the USB memory device.

Make a recording cont.

Files that have been written to the USB memory device are held in a folder called

'REC'. Recordings are given lenames according to the source used for the recording.

The les are named as listed below. Two digits are added to the lename to allow

recordings to be numbered from 00 to 99 for each recorded source. The illustration
to the right shows the folders as they may appear on a PC running Windows with

les in the REC folder.

AUXnn - for recordings from the Auxiliary input
BT_nn - for recordings from Bluetooth devices
DABnn - for recordings from DAB radio
FM_nn - for recordings from FM radio
MEXnn - for recordings from external microphone
MINnn - for recordings from internal microphone

The lenames are created automatically by the radio when recording. In the event
that the lename matches a le already on the USB memory device, then the new
le will be named RECnn.mp3 instead to prevent overwriting the existing le.

Note: The USB memory device should only be removed when recording is stopped.
Removing media while recording is in progress may corrupt data on the USB device

leading to the loss of les previously written.

The USB connection is intended to be used to allow the Opus radio to play les
from solid-state ash memory devices. The USB connection is not intended to be

connected to other USB devices such as computers or hard disk drives.

If you wish to make recordings from radio, we recommend recording from DAB
radio if possible since it is generally less susceptible to interference than FM radio.
If you need to record from FM radio, some interference may be picked up from the
memory device unless you have a strong signal.

A Few Words about Batteries…

Rechargeable batteries

Your Roberts Opus radio has been designed to use a choice of power
sources. You may plug it into the mains using the supplied adaptor,
or for listening away from the mains you may use either alkaline or
rechargeable batteries. We do not recommend the use of carbon-zinc or
zinc-chloride batteries.

It is very important that you read the advice and warnings given

below.

1) Whichever type of batteries you choose to use, it is very important
that the battery selection switch under the cover is set to the correct
type.

a. If no batteries are tted, then set the switch to the Alkaline position

(up). This position minimises the power consumption when the radio
is powered from the mains.

b. If Alkaline batteries are tted, then set the switch to the Alkaline

position (up).

c. If Rechargeable batteries are tted, then set the switch to the NiMH

position (down). Your radio is designed to use Nickel-Metal-Hydride
rechargeable batteries. No other type of rechargeable battery should
be used in the radio.

2) NEVER mix old and new Alkaline batteries. The old batteries may
suffer damage and leak which will damage your radio and whatever
the radio is standing on.

3) NEVER mix old and new Rechargeable batteries. This may
result in unreliable charging and shortened battery life. Never mix
Rechargeable batteries of different types or capacities even if they
are new.

4) NEVER mix Alkaline and Rechargeable batteries. The recharging of
Alkaline batteries can be very dangerous.

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

Danger of explosion if the batteries are incorrectly replaced.

Your Opus radio uses a range of methods to ensure correct and safe
charging of Rechargeable Nickel-Metal-Hydride batteries. These work
to protect your batteries from excessive charge and discharge. These
protections can only work properly if the advice above is followed. In
particular, the radio will not be able to correctly charge batteries if they
are a mixture of different brands, or different ages, or different capacities.

We recommend that all the rechargeable batteries used in your radio
are bought together as a set. They should always be charged together
and discharged together and not “borrowed” from time to time for other
applications. This will ensure that they give their optimum performance
in your radio.

We recommend that the rechargeable batteries that you use should
be from a quality brand, and should be of at least 2500mAh capacity.
Batteries of this capacity should be able to power your radio for between
15 and 25 hours depending upon the volume of the radio, operating
mode and also depending on the condition of the batteries.

Before you rst install a new set of rechargeable batteries into your
radio you should rst make sure that the battery type switch beneath

the battery cover is in the NiMH position (down). Install the batteries
arranging them as shown on page 5.

Plug the mains adaptor into a mains socket and then into the radio. The
charging indicator will show on the display, see page 5.

The time taken to charge the batteries will depend on how much charging

they require. New batteries may be partly charged when rst tted, but

it is normal for a set of batteries to take several hours to charge fully.

Typically this can be between 6 and 10 hours depending on the battery

capacity and their initial state of charge.

If you intend not to use your radio for some months, then we recommend
that the batteries are removed and put away, keeping them in a cool
place out of reach of children, away from moisture and such that no metal
object can contact the battery terminals.

With care, rechargeable batteries can last a long time and can operate for
many hundreds of charge and discharge cycles. When your rechargeable
batteries can no longer power your radio adequately, please dispose of
them thoughtfully.

To avoid danger and risk of injury, please follow
these guide lines

Improper use of batteries may result in leakage of uid, overheating
or explosion. Battery uid is corrosive and may also be toxic. Battery
uid can cause skin burns, can damage the eyes, and can be harmful if

swallowed.

1. Keep batteries out of the reach of children.

2. Do not heat, open, puncture, mutilate or dispose of batteries by
burning.

3. Do not mix different battery types or old and new batteries. Always
replace all the batteries at the same time.

4. Do not carry or store batteries such that metal objects may contact
the end caps.

5. Remove batteries from the radio if they are worn out or if you are
storing it for a long time.

6. Remove old or worn out batteries promptly, and recycle or dispose of

them according to the regulations applicable to your location.

7. If a battery does leak, remove all batteries from the product, taking

care to avoid directly touching the leaked uid. If the uid contacts

skin or clothes wash with water immediately. Before inserting new
batteries, thoroughly clean the battery compartment with a damp
paper towel, or follow the battery manufacturer’s advice for clean up.
