Upgrading your Indirect Ophthalmoscope Power Supply
Introduction
Thank you for purchasing a Keeler Indirect Ophthalmoscope
Power Supply. We have taken the greatest care in the design,
development and manufacture of these devices to ensure that
they give you many years of trouble-free service. However, it is
important that you read the descriptions, installation and operating
instructions contained in this book carefully prior to installing or
using your new Indirect Ophthalmoscope Power Supply.
If you are in doubt about any aspect of these instructions, we
recommend that you contact a qualified electrical technician, your
nearest authorised Keeler Distributor, or Keeler direct.
Indirect Ophthalmoscope Power Supply Units are for indoor
use only. Where appropriate, the plug-in power module of the
power supply unit is designed to be connected directly to a suitable
wall socket. It is important therefore that a socket is selected
where the power module will not be vulnerable to damage from
passing trolleys, etc and the low voltage interconnecting leads
should be kept away from gangways and passageways where
persons would be expected to pass.
Do not use in the presence
of fluids or flammable anaesthetics.
As part of our policy for continued product development we reserve the
right to amend specifications at any time without prior notice.

Ophthalmoscope Power Supply
1.2 Electrical Check
Before connecting the power unit to the electricity supply,
check that the input voltage on the data rating label corre-
sponds with that of your local supply voltage. For full electri-
cal information and circuit diagrams, refer to Section 5 - Tech-
nical Specification.
1.3 Fitting Instructions for Desk-Top Use
Keeler Indirect Ophthalmoscope Power Supply systems are
supplied ready assembled for desk-top use. Place the unit
in the desired position and plug the power module into a suit-
able power outlet/wall socket. Your power supply unit is now
ready to accept Keeler Indirect Ophthalmoscopes. Refer to
section 2 - Standard Operating Instructions.
1.4 Fitting Instructions for In Case Use
Keeler Indirect Ophthalmoscopes may be operated direct
from the case for short periods by plugging the power mod-
ule into a suitable nearby power outlet/wall socket.
CAUTION
Care should be taken not to close the case lid when the
instrument is being used in this way as this may cause
damage to the connecting cables.
Alternatively, the Indirect Ophthalmoscope Power Supply may
be removed from the case and operated from the desk or
wall mounted (see 2.1)
1.5 Fitting Instructions for Wall Mounted Systems
Important Notice: Keeler Indirect Ophthalmoscope Power
Supplies are designed to be fitted to all walls. The wall fit-
tings supplied are suitable for mounting your power supply
to walls constructed of sound brick, breeze block, concrete
Preparing your Indirect
Ophthalmoscope Power Supply
or plasterboard. If required alternative fittings suitable
for mounting your power supply on walls constructed from
materials other than those mentioned above should be ob-
tained. If in doubt, consult a qualified builder for advice.
Keeler Limited cannot accept any responsibility for any
damage or injury sustained by incorrect assembly, wall
mounting or use of wall mounted power supplies.
The Keeler transformer unit must be disconnected from the
power supply before commencing to wall mount the unit.
a) To wall mount your Keeler Power Supply, select a convenient
position on the wall ensuring that there is a suitable power
outlet/wall socket for the plug-in power module within reach
of the interconnecting cord. Also, make sure that there are
no water or gas pipes or electrical cables buried in the wall.
b) Refer to the chart over the page (Fig.2) and identify your
power supply unit. Remove the module(s) shown from the ‘L’
shaped rail to expose the wall mounting fixing holes. This
canbe done by first removing the plastic screw hole covers
and unscrewing the retaining screws using the hex-
agonal Allen key provided. Keep the retaining screws safe
for later reassembly.

a continuous period of 24 hours.
The full charge capacity will be obtained after 3 or 4 full
charge/discharge cycles. This should also be carried out
when batteries have been stored for long periods in a fully
discharged state. After repeated charge/discharge cycles it
is possible for a reduction in battery capacity
parent. The normal capacity can be restored by a period of
extended charge (24 hours) as described for new batteries
above.
2.3 Connecting your rechargeable battery for use

Care and Maintenance
Leaving the illumination on for long periods when not in use
reduces the remaining life of the Halogen Bulb in your
instrument. We therefore recommend returning the indirect
to its cradle or switching off at the control when not in use.
