INTRODUCTION
The T4000 RF module is a Tri Band transceiver assembly that operates in 136 – 174, 380 – 520, and
764-870 MHz ranges. The T4000 RF module is a modified Motorola APX 8000 Tri Band portable radio.
The outer casing, top controls, front display and keypad are removed. The RF chassis is slightly
machined but all electronic circuits are unmodified from the original APX 8000 radio.
The transceiver is designed to be installed and operated in a Technisonic Multiband Airborne Radio
TDFM 9000 platform. All external power and antenna connections are provided by the TDFM 9000 as
well as controls are via the front panel and display from the TDFM 9000.
The RF module is capable of operating on Analog FM, Wide and Narrow and Project 25 Phase 1
conventional and P25 Trunked Phase 1 and 2 systems.

NOTES
ESD CAUTION
This unit contains static sensitive devices. Wear a grounded wrist strap and/or conductive gloves
when handling printed circuit boards.
FCC COMPLIANCE INFORMATION
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and (2) this device must accept any interference
received, including interference that may cause undesired operation.
WARNING: For compliance with FCC RF Exposure Requirements the mobile transmitter
antenna installation shall comply with the following two conditions:
1. The transmitter antenna gain shall not exceed 3 dBi.
2. The transmitter antenna is required to be located outside of a vehicle and kept at a separation distance of 90 cm
or more between the transmitter antenna of this device and persons during operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.

“TDFM-9000 FINAL ASSEMBLY SSP".
FCC ID LABELS
The T4000 RF module is a modified Motorola APX 8000. Part of the modification requires removal if the
original Motorola FCC ID label. After all modifications are done the new Technisonic FCC/IC ID label is
applied.

The FCC/Industry Canada label is shown below. It is mounted on the top near the front of the module.
FIGURE 3: T4000 FCC/Industry Canada Label
FIGURE 4: FCC/Industry Canada Label placement on the T4000 Module
The T4000 is intended to be mounted in the TDFM 9000 chassis and is not visible. Therefore, a second
label must be applied to the outside of the TDFM 9000 that contains the following text:
“TDFM 9000 Multiband Transceiver. Contains Module: FCC ID IMA-T4000”.
In addition, external labeling for Industry Canada shall be applied to the TDFM 9000 to include the
following text: “Contains IC: 120A-T4000”.
WARNING AND DISCLAIMER
Changes or modifications not expressly approved by Technisonic Industries could void the user’s
authority to operate the equipment.
