PTRL NV/3 & RXRL NV/3
When the machine reaches the maximum temperature allowed, output power will be
reduced gradually. A 5°C margin for overheating normally allows for emergency
operation at limited power.
Please note that the higher the ambient temperature, the shorter the average unit life:
service life is nearly halved with each 10° C increment in temperature. Assuming 10
years service life at +25°C - a realistic estimate - at +45°C unit life will be 2.5 years
shorter.
9.5.12 Quadro #10: Internal voltages
This screen shows internal operating voltages.
Vs+ and Vs- are the same throughout the radio link transmitter family and are as
follows: Vs+ = +12.5±0.3V, Vs - = -12.4V (+1/-2V).
Battery voltage is: Vbat= +27.4V ±0.5V when the battery is fully charged. When
fed from the battery, the unit will require a voltage within a 22 to 28V range in order to
operate.
9.5.13 Screen #11: Time counter
This screen shows how long the transmitter has been in the on-the-air or in the stand-
by mode. Its reading may not be modified
9.6 Transmitter Setup menu
