Introduction
The OML LINQTM enables a wireless link to be set up between an
Odstock Medical Wired Footswitch and an Odstock Medical wireless
enabled stimulator such as the ODFS®Pace XL. Uniquely the OML
LINQTM can have two Wired Footswitches attached allowing for
additional triggering options (refer to the OML LINQTM: Addendum for
Clinicians). The OML LINQTM has been designed to allow the user
to set the device up with their wireless stimulator. However some
functions identified in this manual require a clinician to set them up.

Precautions
1. Warning: keep the OML LINQTM components out of reach of
babies and children. The OML LINQTM is not a toy!
• Components of the OML LINQTM are a choking hazard.
• Battery is extremely hazardous if swallowed. Seek
immediate medical attention.
• Wires of the Wired Footswitch are a strangulation hazard.
2. Ensure that a suitable Wired Footswitch length is used so that
the user does not catch excess wire on themselves or other
objects.
3. Replace Wired Footswitch if lead becomes stiff or damaged.
4. Warning: battery may explode if mistreated. Do not recharge,
disassemble or dispose of in fire.
5. The OML LINQTM should be securely mounted especially if
used for jogging/running.
6. The OML LINQTM is splashproof but must not be submerged.
7. The OML LINQTM must not be dis-assembled by anyone other
than Odstock Medical Limited. Doing so will invalidate the
warranty.
8. The OML LINQTM must not be modified by anyone other than
Odstock Medical Limited. Doing so will invalidate the warranty.
9. The OML LINQTM must only be used with Odstock Medical Ltd
products.
10. Before use check that the OML LINQTM has no visual signs of
damage.

5
11. The Wired Footswitch should be securely mounted to either the
insole provided or within the shoe.
12. Like all wireless devices the OML LINQTM should not be used
in areas where wireless is prohibited (e.g. aircraft). The OML
LINQTM should be carried in luggage with the battery removed
from the device. Revert to using the stimulator with a Wired
Footswitch.
13. Whilst driving ensure that the OML LINQTM is not in a position
where it could be knocked or dislodged or affect foot pedal
operation.
14. Do not over bend the clip of the Holder. Remove the Holder
from the shoe by sliding upwards only.

6
1. Ensure that the OML LINQTM is positioned correctly in the
Holder.
2. Push the OML LINQTM into the Holder ensuring that both arms
click into place into the slots on the side of the device.
The Holder allows the OML LINQTM to be attached to the side of
a shoe or sock. Ensure that it is securely attached before use!
When removing the Holder from the shoe be careful not to over
bend the clip. Slide the Holder upwards, off the rim of the shoe.
The OML LINQTM can be used without the Holder and placed directly
in a sock.

Installing a Battery
WARNING: replace the battery with a CR2430 coin cell only.
Remove battery if the device is not to be used for an extended
period of time, such as 1 month.
1. Turn the stimulator off and then back on.
2. Remove OML LINQTM from the Holder if attached (see page 7).
3. Slide open the battery cover. The cover slides away from the
OML LINQTM. Press down on the rear portion of the cover to
release the clip (please refer to image A and B).
4. If present then remove the old battery.
5. Install the new battery with the positive side of the battery
facing out from the OML LINQTM. If installed correctly the blue
light will flash once (please refer to image C).
6. Slide the battery cover back on to the main body. The battery
cover is fully inserted when there are no gaps between the
casing and the battery cover (please refer to image D). Do not
use excessive force.
7. Re-insert the OML LINQTM into the Holder (see page 6), insert
the Wired Footswitch and check that the stimulator unpauses
and responds to a press of the footswitch (see page 12).

Joining Instructions
Use this process if the OML LINQTM is not joined to the stimulator
or when the OML LINQTM is provided separately from the
stimulator.
NB. Ensure that the OML LINQTM does not contain a battery prior
to starting this process.
1. Insert a battery into the OML LINQTM and close the battery cover.
2. Ensure that the stimulator is turned on.
3. Select the joining option from the wireless menu on the stimulator
(refer to stimulator user instruction manual or OML LINQTM:
Joining to ODFS®Pace XL quick start card supplied).
4. When the stimulator indicates that it is waiting to join (this will
time out after 1 minute), press and release the joining button on
the OML LINQTM. A successful press of the button will result in
the blue light flashing for up to 1 minute.
5. Bring the stimulator and OML LINQTM close to each other.
6. After a few seconds the stimulator will indicate that joining has
been successful and the blue light on the OML LINQTM will stop
flashing.
7. Your OML LINQTM is now joined.
If unsuccessful repeat this process.

Installing a Wired Footswitch
Prior to inserting the footswitch plug into the socket make sure
that there is no debris in the socket of the OML LINQTM.
Insert the Odstock Medical Wired Footswitch into either socket of the
OML LINQTM. Your clinician will set up the position of the footswitch
in your shoe/insole for reliable operation.
If using a single footswitch it does not matter which socket the
footswitch is inserted into.
NB. Two Odstock Medical Wired Footswitches can be used on
the OML LINQTM. This replicates the function of the OML double
footswitch setup. Please refer to the OML LINQTM: Addendum for
Clinicians card.
If this functionality is required then this can be setup by your
clinician. Warning: do not attempt to set this up yourself. This
should only be set up by a trained clinician.

13
Use and Care Instructions
Normal Use
Normal use of the OML LINQTM is defined as wearing the device in
the Holder mounted to either a shoe or sock. Alternatively, the OML
LINQTM can be used without the Holder and placed directly in a sock.
Warning: if you have latex or rubber allergies do not use against
the skin.
Care Instructions
The OML LINQTM can be cleaned using a damp cloth. Do not
immerse in water or use solvents.
If the OML LINQTM becomes wet please remove the battery cover
and battery and allow to air dry thoroughly for 24 hours before re-
use. If unresponsive contact Odstock Medical Limited.
Expected Service Life
The OML LINQTM has an expected service life of 2 years. After this
period it may be necessary to replace the device. The sockets of the
OML LINQTM may require replacement during the life of the product
due to daily wear.
FES Support Group
There is a web based discussion group for users of Odstock Medical
FES devices. Visit www.odstockmedical.com for information on how
to join the group.

Miscellaneous
Activity and Inactivity Detection
To save battery power the OML LINQTM goes into a sleep mode
when no activity is detected for 5 minutes or more. The device is
woken up by any small motion of the OML LINQTM or by pressing
the Wired Footswitch. If no movement occurs before pressing the
pause on the stimulator to begin walking, the OML LINQTM may not
be detected by the stimulator. If this occurs a small movement of the
foot or force on the Wired Footswitch will wake up the OML LINQTM.
Turning o󰀨 the OML LINQTM
There is no off switch on the OML LINQTM. The device will enter a
low power state if it is not being used but if it is not to be used for an
extended period (i.e. 1 month), then remove the coin cell battery.
Close Proximity Joining
Close proximity joining is used if many devices are being joined at
the same time in a confined space (e.g. a clinical area). If a Wired
Footswitch is inserted and pressed down at the same time that the
joining button is pressed then close proximity joining will start. This is
indicated with the blue light flashing quickly. The two devices should
be positioned touching each other for joining to be successful.
Transportation
Odstock Medical Limited recommend transporting the OML LINQTM
without a battery installed to turn off wireless communication (e.g.
on an aircraft). In this case use the stimulator in Wired Footswitch
mode. Warning: Please check with local authorities/regulations
on the requirements for transportation of lithium batteries.

15
