User's Manual

If the pump is dropped, hit against a hard object, or otherwise damaged, the
waterproof characteristics of the outer casing of the pump may be compromised.
If your pump has been dropped or you suspect your pump is damaged, carefully
inspect your pump to ensure there are no cracks before exposing your pump to
water.
If you believe that water has entered your pump or you observe any other
possible pump malfunction, check your blood glucose, and treat high blood
glucose as necessary, using an alternative source of insulin. Contact your local
representative for further assistance. Always contact your healthcare professional if
you experience excessively high or low blood glucose levels or if you have any
questions about your care.
Electrostatic discharge
Although your MiniMed 640G insulin pump is designed to be unaffected by typical
levels of electrostatic discharge (ESD), very high levels of ESD can result in a reset
of the pump's software and a pump error alarm. After clearing the alarm, verify
that your pump is set to the correct date and time and that all other settings are
programmed to the desired values because the software reset could erase your
previously programmed settings.
For more information on pump alarms, see Pump alarms, alerts, and messages, on
page 202. For more information on re-entering your pump settings, see My pump
is asking me to enter my settings, on page 232. If you are unable to re-enter your
pump settings, or otherwise believe there is a problem with your pump, contact
your local representative.
Avoid extreme temperatures
Exposure to extreme temperatures can damage your device, which can adversely
affect safety and effectiveness of your device. Avoid the following conditions:
1. Avoid exposing your pump to temperatures above 40 °C (104 °F) or below 5
°C (41 °F) because this may damage your device.
2. Insulin solutions freeze near 0 °C (32 °F) and degrade at high temperatures. If
you are outside in cold weather, wear your pump close to your body and
cover it with warm clothing. If you are in a warm environment, take measures
to keep your pump and insulin cool.
