ﬁt) are potentially dangerous, may be damaged during walking, and cause erroneous measurement

values. Check the proper ﬁt of the sensor insole after insertion into the shoe.

The sensor insole may only be worn in closed footwear.

The battery compartment must face down towards the ﬂoor when inserting the sensor insole into a shoe.

Immediately stop wearing sensor insoles in case of pain or skin irritation.

The weight of the patient wearing the sensor insole may not exceed 120 kg.

Remove the battery from both insoles after ﬁnishing a measurement, or when the battery is not used

for some time. Store the sensor insole only without battery.

In case of an internal fault, surface temperatures of 41 ◦C to 43 ◦C may occur, constituting a possible

temperature hazard.

The sensor insole may not be worn with open wounds or ulcers.

The sensor insole must be worn with socks in order to avoid direct skin contact.

Never use batteries other than batteries provided by Moticon for your sensor insoles. They are labelled

as follows: Route JD Inc Li-ion Rechargeable 3.7V

Do not use the sensor insole in case of a damaged, demolished or shifted battery contact.

Do not use the sensor insole with open battery compartment.

Do not remove the battery during a measurement. For longer measurements, instruct the patient to

not remove the battery and to not remove the battery lid.

Do not use sharp objects for removing the battery. Only use the tip of the ﬁnger.

Only insert fully charged batteries into sensor insoles, otherwise the battery level indicator in the software

of the controlling device will display wrong values.

How to insert the battery into the sensor insole:

1. Make sure that positive (+) pole of the coin cell battery points towards you. With this orientation, slide

the coin cell battery under the contact ﬂap.

2. Sink the battery into the battery case by gently pushing it downwards.
