8 Module Replacement During Servicing (Only for Level 2

Service Partners!)

Note: This chapter describes the service activities at Service Level 2. These activities may

only be undertaken by skilled staff trained to Level 2 by Swissphone.

8.1 Important Notes

The ESD guidelines for the protection of electronic components against electro-static phe-

nomena must be observed in accordance with DIN EN 61340-5-1. Always touch the

ITC2100 housing with one hand first before handling the relevant module. This discharges

electrostatic voltage and so prevents damage to the electronic components.

Module replacement does not extend the existing guarantee or guarantee periods. The

module replacement does not renew guarantees or guarantee periods which have already

expired.
