Battery operation using alkaline batteries
(also see page 25)
1. Remove the battery cover on the back of the unit by pushing the battery
door in slightly and then downwards in the direction of the arrow.
2. Slide the switch inside the battery compartment to the Alkaline
position.
3. Insert four LR6 (AA size) Alkaline batteries into the spaces in the
compartment. Take care to ensure all batteries are inserted with the
correct polarity as shown inside the battery compartment. Then replace
the battery cover.
• Important: when using Alkaline batteries the battery switch must
be placed in the Alkaline position. Failure to do so could result
in serious damage to the batteries or radio.
• When the batteries are exhausted, the charge/low battery indicator
will show red 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
replaced, or until the radio is connected to the mains adaptor.
• 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 Revival Mini is used via
the AC adaptor whenever possible with battery operation for occasional
use only. If extended listening using batteries is anticipated, then the
use of rechargeable batteries is recommended.
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.

Battery operation using rechargeable batteries
Service
(also see page 25)
The rst few times that you charge a new set of batteries, you may nd that the charge and play times are very short. Normal operation
should be achieved after 3 or 4 charge - discharge cycles.
Batteries are only charged while the radio is connected to the mains supply via its adaptor and it is switched off using the On/Off button.
1. Remove the battery cover on the back of the unit by pushing the battery
door in slightly and then downwards in the direction of the arrow.
2. Slide the switch inside the battery compartment to the NiMH
position.
3. Insert four Rechargeable LR6 (AA size) batteries into the spaces in the
compartment. Take care to ensure all batteries are inserted with the correct
polarity as shown inside the battery compartment. The radio is designed
to be used with Nickel Metal Hydride (NiMH) rechargeable batteries. Then
replace the battery cover.
4. Plug the mains adaptor into your radio and then plug the adaptor into the
mains.
5. The Charge light will ash green indicating that the batteries are charging.
Batteries will be fully charged in around 3 - 7 hours depending on their
capacity. The charge light shows a steady green light when the battery
charging is complete. The display will show "Battery Full".
6. Under some conditions the charging indicator light may switch off after
ashing only briey. This may happen if the batteries are already freshly
charged, or if the radio detects that you may be attempting to recharge
alkaline batteries. In these cases the charging will be stopped.
If the charge process stops after only a short while this may be due to
a faulty battery. In this case the display will show "Battery Fail" and the
battery number 1-4, corresponding to the numbering printed inside the
battery cover.
If this happens, try charging the batteries a second time by removing and
reconnecting the AC power adaptor. If the message is repeated, then it is
likely that the batteries are old and should be replaced.
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. Batteries
will only be charged when the radio is switched off and
connected to the AC adaptor.

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.
• 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.
Using the AC adaptor
1. Insert the adaptor plug into the DC in socket on the rear of your radio.
2. Plug the adaptor into a standard mains socket outlet. Whenever the
adaptor is plugged in to the radio and switched on at the mains the
batteries are automatically disconnected. If the adaptor is plugged in to
the radio but not switched on then the radio will run from the batteries
if tted.
The AC adaptor should be disconnected from the mains supply and
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.
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.

A Few Words about Batteries…
Rechargeable batteries
Your Roberts Revival Mini radio has been designed to use a choice of
power sources. You may plug it into the mains using the supplied high-
efciency 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.
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.
c. If Rechargeable batteries are tted, then set the switch to the
NiMH position. 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.
Your Revival Mini 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 power your radio for between 15 and
20 hours depending upon the volume of the radio, whether DAB or FM
mode is used (DAB mode uses slightly less power than FM), and also
depending on the condition of the batteries. Higher capacity batteries are
available and will give longer life, but will generally be more expensive.
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. Install the batteries arranging them
as shown inside the battery compartment. Plug the mains adaptor into the
radio and then into the mains socket. While the batteries are charging the
charge indicator should show a ashing green light. When the batteries
are fully charged the indicator will stop ashing and will show a steady
green light. 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 (this can be between 3 and 7 hours depending on the battery
capacity and their initial state of charge).

Your radio will display a message at the end of the charging process. If
the charging is successful, or if the batteries are nearly fully charged, the
display will show "Battery Full".
If the charge process stops after only a short while this may be due to
a faulty battery. In this case the display will show "Battery Fail" and the
battery number 1-4, corresponding to the numbering printed inside the
battery cover.
If this happens, try charging the batteries a second time by removing and
reconnecting the AC power adaptor. If the message is repeated, then it is
likely that the batteries are old and should be replaced.
If you use the radio powered from the batteries, the charge/low battery
indicator light will be off until the batteries are exhausted. The charge/
low battery indicator light will then show red for a short while before the
radio switches itself off. It does this in order that the batteries are not
excessively discharged. This would otherwise damage the batteries and
shorten their life.
If you use the radio powered from the mains with rechargeable batteries
tted, the charging process is suspended until you switch off the radio.
When you switch off the radio using its On/Off button charging will then
resume. If the batteries have already been charged then they will only
charge for a few more minutes before the charge indicator stops ashing.
If you only listen to your radio for short periods, you do not need to
connect your radio to the mains to charge the batteries every time that
you use it. However, if the radio is not to be used for a few weeks, then
we recommend that the batteries are fully charged (charge light shows
steady green) before the radio is put to one side.
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 responsibly using a local battery recycling facility.
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.

Display backlight
1. When using the radio powered from batteries, the display backlight
will be switched on for approximately 12 seconds when any button is
pressed.
2. When your radio is powered by the AC mains using the supplied mains
adaptor the display backlight will always be on whenever the radio is
switched on.
3. The display backlight will also be on when a battery message is
displayed (see page 5).
