PREPARATIONS AND CONTROLS Norge If the fitted plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place.

Typeskilt finnes på apparatens underside. Note: The severed plug must be disposed of to avoid a possible shock hazard should it be inserted into a 13 Amp socket elsewhere. Observer: Nettbryteren er sekundert innkoplet. Den innebygde netdelen er derfor ikke frakoplet nettet så lenge apparatet er tilsluttet nettkontakten. 1-9 How to connect a plug The wires in the mains lead are coloured with the following code: blue = neutral (N), brown = live (L). For å redusere faren for brann eller elektrisk støt, skal apparatet ikke utsettes for regn eller fuktighet. ¶ As these colours may not correspond with the colour markings identifying the terminals in your plug, proceed as follows: ­ Connect the blue wire to the terminal marked N or coloured black. ­ Connect the brown wire to the terminal marked L or coloured red. ­ Do not connect either wire to the earth terminal in the plug, marked E (or e) or coloured green (or green and yellow). CAUTION Before replacing the plug cover, make certain that the cord grip is clamped over the sheath of the lead - not simply over the two wires. Use of controls or adjustments or performance of procedures other than herein may result in hazardous radiation exposure or other unsafe operation. Copyright in the U. K.

Do not use solvents such as benzene, thinner, commercially available cleaners, or antistatic spray intended for analogue records. Cleaning the Heads and the Tape Paths To ensure good recording and playback quality, clean the heads A, the capstan(s) B, and pressure roller(s) C after every 50 hours of tape operation. Caution: Do not rotate the heads during cleaning. Use a cotton swab slightly moistened with cleaning fluid or alcohol. You can also clean the heads by playing a cleaning tape once. ­ Clean deck parts, see "Maintenance".
