1. SAFETY INFORMATION
LITHIUM BATTERY NOTICE
This warning is stated on the product or in the operating instructions.When replacing the lithium batteries, follow the note below.Dispose of the used battery promptly. Keep away from children. Donot disassemble and do not dispose of in fire.The battery used in this device may present a fire or chemical hazardif mistreated. Do not recharge, disassemble, heat above 100 ˚C orincinerate. Replace only with the same Part Number. Use of anotherbattery may present a risk of fire or explosion.
Note: The lithium battery installation position is shown in theexploded views.
Denne advarsel or angivet på produktet eller i brugsvejledningen.Ved udskiftning af lithium batterierne følges nedenståendeanveisning.Batterierne må kun udskiftes med batterier af samme type ogmærke.
WARNING!Lithium batteries. Danger of explo-sion. Replacement must be done by qualified personnel and only by fol-lowing the instructions given in the service manual.
ADVARSEL!Lithiumbatteri − Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. Levér det brugte batteri tilbage til leverandøren.

5. PCB PARTS LISTNOTES : ÷ Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.
÷ The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation.
÷ When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by
