3.1.11 Programming with user program. NIROS TRX 1012 is programmed via a CH100 charger supplied with PC interface. Dismount the rubber plug from the external connector of the radio. The external connector from the charger shall be mounted in the radio.
TIONS, DO NOT PERFORM ANY SERVICING ON THE RADIO CIRCUITS UNLESS YOU ARE QUALIFIED TO DO SO. 5.1 Introduction. This section of the manual contains maintenance and adjustment information for the NIROS TRX 1012 transceiver. NOTE! A visual inspection should always precede alignment or repair. Always switch off power or remove battery pack before disassembly or replacement of parts.
It is necessary with access to the inside of the radio to change the connector. See section 6. Use some LOCKTITE 270 (BLUE) at the antenna connector thread to lock the nut. 5.2.6 Display. Display, with NIROS print, NIROS NO. 98095. LCD display NIROS NO.
No self discharge but greatly reduced service time. Apply two or three charge/ discharge cycles and test capacity. It is only allowed to discharge the battery to 6,0 V. NIROS can deliver a CH100 charger supplied with a discharge section.
+/- 400 Hz Capacitors with N750 temperature coefficient are used for some capacitors in D radio version. Change only to exact the same type during service. D-versions: No. Code Value TC (ppm) NIROS NO. C323 150 pF N750 20819 C324 150 pF...
D-versions: Min. 1,7 V - max. 8,6 V at band edges. If the VCO is defect NIROS recommend to order a new one. Specify unit no., frequency segment and channel separation. The VCO needs special tools for disassembly and assembly and contains special capacitors to avoid microfoni.
VCO housing especially if the frequency range is changed more than 10 MHz. The brass core must not be adjusted above VCO top surface or more than approx. 2 turns below coil form top. If a VCO can not be adjusted at the coils. Order a new VCO from NIROS. 5.13 Display.
