4.2) POWER-UP
Warning: before power up, make sure that the isolation between the donor antenna and the
service antenna is at least 15dB greater than the repeater gain.
1. Connect the cable from the donor antenna to a spectrum analyzer and check input signal presence and
level. After measurement disconnect the spectrum analyzer.
2. Switch on the equipment by means of the switches placed inside the repeater (FIGURE 1a and b).
3. Check the LEDs status on the management module: FIGURE 4 and Table 3 show LEDs status on the
management module under normal operating conditions.
