Page 5: General
There are 2 distinct models in the UT-4B Transmitter family each with different bands of operation. The 2 models are as follows: • UT-4B420-00-000 - 406-430 MHz band, 2.0-8.0 Watt • UT-4B460-00-000 - 450-470 MHz band, 2.0-8.0 Watt The transmitters' band of operation is determined by select components in the amplifier. -

Gold plated module connectors. Module Design: Compact Eurostandard modular design. Plug-in modules mate with Daniels standard M3 repeater subrack. Subracks / modules comply with IEEE 1101, DIN 41494 and IEC 297-3 (mechanical size / modular arrangement). External Connections: RF Connection: type N connector located on the transmitter module front panel. -
Page 9: Theory Of Operation
*** Note that the current version of Radio Programming Software is a demonstration version only, and cannot be used to program a Transmitter. To program a Transmitter, use Motorola’s Radio Service Software (RSS), a Motorola Radio Interface Box (RIB), and a Daniels Programming Cable. -
Page 10: Transmitter Wide Options
The transmitter’s frequency band is set here. The available options are 132 – 174 MHz and 406 – 470 MHz. The band from 803 – 870 MHz will become available in future models. DANIELS ELECTRONICS UT-4B400 P25 Digital UHF Base Transmitter Instruction Manual... -
Page 11: Channel Wide Settings
This option enables a Reverse CTCSS Burst to be sent at the end of a transmission. The Reverse Burst signals to the receiving radio that the transmission is ending, allowing it to mute more quickly. 2.2.2.6 DCS Code One of eighty-six DCS codes may be selected here.

Page 13: Nac Transmitter Code
Therefore, it is recommended that Motorola’s Radio Service Software (RSS) and Radio Interface Box (RIB) be used in conjunction with a Daniels Radio Programming Cable to program the transmitter modules. For instructions on how to use the RSS, consult Motorola’s Astro Portable / Mobile Radio Software User’s Guide. -
Page 14: Secure Communications
To transmit a secure signal, the transmitter must be programmed with the correct encryption key using a Motorola KVL keyloader in conjunction with a Daniels Keyloader Cable. Consult the instructions for the Keyloader for details on loading a key. A loaded key may be cleared by pulling first the CLEAR KEYS 1* then the CLEAR KEYS 2* inputs to ground about 500 ms apart. -

2885 Hz. Click on the "UPDATE SOFTPOT" button to save the new setting to the radio's non- volatile memory. Repeat the process for each test frequency. This completes the adjustment process for the transmitter deviation limits, and completes the alignment process for the Main Board.
