Battery Operation - Roberts Stream 218 Manual List

Battery operation

We recommend for economy that the Stream 218 is used with the AC
adaptor whenever possible with battery operation for occasional use only.
Inserting the adaptor into the DC input socket will disconnect the batteries.
If using batteries, only alkaline types should normally be used. Battery life
will vary according to the operating mode of the radio, listening volume,
battery type and temperature. Using quality branded Alkaline batteries,
between 40 and 75 hours should be possible. WiFi takes much more
power than DAB listening for example.
To install batteries in your radio follow these steps.
1. Remove the battery cover on the rear of the unit by pushing the battery
door in and downwards.
2. Insert six LR20 (D 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.
3. Replace the battery cover.
Reduced power, audio distortion or the radio switching itself off are all
signs that the batteries may need replacing.
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.
Rechargeable Nickel Metal Hydride (NiMH) cells can be used in the radio
but must be charged outside the radio using an external charger. Note
that readily available D size NiMH cells have a capacity which is only a
small fraction of that of D size Alkaline cells and so they will power the
radio for only a few hours before needing recharging. Never mix batteries
of different types, capacities or brands in the radio.
IMPORTANT: The batteries should not be exposed to excessive heat
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.
