fromtheclock,theuserisencouragedtotrytocorrecttheinterferencebyoneormoreofthe
followingmeasures:
1. ConnecttheACpowercordintoanoutletonadifferentcircuitthanotherdevices.
2. Increasethephysicaldistancebetweentheclockandotherdevices.
3. Contacttechnicalsupport.


ThisCLKTCDanalogclockhasbeentestedandfoundtocomplywiththelimitsforaClassB

reasonableprotectionagainstharmfulinterferenceinaresidentialinstallation.
Onlyqualifiedpersonsareauthorizedtocarryoutmaintenanceonthisdevice.ReadthisUser’s
Manualcarefully,andfollowthecorrectprocedurewhensettingupthedevice.Donotopenyour
Masterclockproductorattempttodisassembleormodifyit.


Neverinsertanymetallicobjectintotheclockscase,doingsoincreasestheriskofelectrical
