Table 6-2. Transmit Power Setting - Motorola MCS 2000 Service Instructions Manual

6-4
800/900 MHz Models only:
Each 800 MHz model is subdivided into three power levels. The upper power level is the high power
level setting and corresponds to the left-most column in the RSS TRANSMIT POWER MENU. The
middle level corresponds to the second from left column in the RSS TRANSMIT POWER MENU
which is the mid power level setting. The lower level refers to the low power level setting which
corresponds to the second from right column in the RSS TRANSMIT POWER MENU. The right most
column in the RSS TRANSMIT POWER MENU is fixed at DAC=63.
• The high power output is tuned for each frequency.
• The mid power is tuned as follows:
- 800 MHz 15 W: all frequencies tuned.
- 800 MHz 35 W and 900 MHz 30 W: the third frequency is tuned and all other frequencies
are copied from this.
- 900 MHz 12 W: the first, second, fifth and sixth are tuned. The third frequency setting is
copied from the second and the fourth is copied from the fifth.
• The low power is not tuned and the default settings are:
- DAC=44 - 800 MHz.
- DAC=43 - 900 MHz.
NOTE: After POWER tuning, measure and note the DC current to the radio on each channel in the
high power level. These values are needed for the Current Limit tuning.
• The larger the softpot values, the lower the transmit power.
