To enter a frequency from the MH-48A6J keypad, just press the numbered digits on the in the proper sequence. There is no “decimal point” key on the MH-48A6J keypad, so if the frequency is below 100 MHz (e.g. 29. 480 MHz), any required leading zeroes must be entered.

Examples: To enter 29.480 MHz, press [0] Æ [2] Æ [9] Æ [4] Æ [8] Æ [0] To enter 433.000 MHz, press [4] Æ [3] Æ [3] Æ [0] Æ [0] Æ [0]

3) Scanning

From the VFO mode, press the [SCN] key momentarily, the FT-8900 will begin scanning toward a higher frequency, and will stop when it receives a signal strong enough to break through the squelch threshold. The FT-8900 will then hold on that frequency according to the setting of the resume mode (Menu #36 [S C A N]).

If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction while the FT-8900 is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL kno b one click clockwise.

Press the [SCN] key again to cancel the scanning.

Transmission

The FT-8900 includes a number of features which make repeater operation simple and enjoyable.

Repeater Shifts

station(s) transmitting on the repeater uplink (input) frequency in order to allow Tone Search Scanning to work.

To scan for the tone in use:

1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous

PERATING MANUAL

To reducing the microphone input level as follow:

1. Press the [SET] key momentarily to enter the Set mode.

2. Rotate the “Main” DIAL knob to select the Menu #45 (WID.NAR).

3. Press the “Main” DIAL knob momentarily, then rotate the “Main” DIAL knob to

change the display to “WIDE.”

4. Press and hold the “Main” DIAL knob for 1/2 second to save the new setting and to

normal operation.

To restore the normal (higher) microphone input level and normal (15 kHz) receiver bandwidth, select “WIDE” in step 3 above.

Programming the key assignment

Programming the key assignmentProgramming the key assignment Default FT-8900R key functi ons have been assigned to Microphone’s [P1]/[P2]/[P3]/[P4] buttons at the factory. These may be changed by the user, if you wish to make another function.

To programming the function:

1. Press the [SET] key momentarily to enter the Set mode.

2. Rotate the “Main” DIAL knob to select the Menu Item to be assigned (“#29 PG P1,”

“#30 PG P2,” “#31 PG P3,” or “#32 PG P4”).

3. Press the “Main” DIAL knob momentarily, then rotate the “Main” DIAL knob to

select the function you wish to assign to the button you selected in the previous step. The available choices are: SQL.OFF: Open the Squelch on the “Main” band to allow un-muted reception. TCALL: Activates 1750 Hz Tone Burst. RPTR: Selects Repeater Shift direction on the “Main” band. PRI: Activates the Priority feature on the “Main” band. LOW: Selects the transmit power output level on the “ M ain” band. TONE: Activates the CTCSS or DCS operation on the “Main” band. MHz: Allows tuning in 1-MHz step on the “Main” band VFO. REV: Reverses the transmit and receive frequencies during split-frequency

operation. HOME: Switches operation to the “Home” channel on the “Main” band. BAND: Select the “Main” band of operation between “Left” band and “right”

“Main” band.

4. Press the [SET] key to save the new setting, then rotate the “Main” DIAL knob to select another programmable button to modify, if desired, and repeat the above steps.

5. Press and hold the “Main” DIAL knob for 1/2 second t o exit to normal operation.

DCS Code Inversion

DCS Code InversionDCS Code Inversion The DCS system was first introduced in the commercial LMR (Land Mobile Radio) service, where it is now in widespread use. DCS is sometime referred to by its different proprietary names, such as DPL® (Digital Private Line®, registered trademark of motorola, Inc.).

DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data rate of 134.4 bps (bit/sec). Occasionally, signal

inversion

can result in the

complement

of a code to be sent or received. This prevent receiver squelch from opening with DCS enabled, as the decoded bit sequence would not match that selected for operation. Typical situatio ns that mig ht cau se inversion to occur are:

 Connection of an external rece iver preamplifier.  Operating through a repeater .  Connection of an external linear amplifier.

not

Note that code inversion does

mean that any of the above listed equipment is

detective !

In certain amplifier configuration s, the output sign al (pha se) is inverte d from the in put. Small signal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification stages may result in inversion of a transmitted or receive d DCS code.

While under most circumstances this should not occur (amplifier designs and industry standards take this into account), if you find that your receiver squelch does not open when both you and the other station are using a common DCS code, you or the other station (

1. T u rn the radio off.

2. Press and hold in the “left” and “right” [V/M] keys while turning the radio on.

3. Rotate the “right” DIAL knob to select the resetting menu:

SETMOD RESET: reset the Set (Menu) mode settings to their factory defaults. HYPER RESET : clear the Hyper Memories settings to factory defaults. MEMORY RESE T: clear the Regular Memories settings to factory defaults. ALL RESET: clear the all memorie s and other settings to fact ory def au lts.

4. Press the [SET] key momentarily to reset to their factory defaults.

Cloning

CloningCloning You can transfer all data stored in one FT-8900 to another FT-8900 by utilizing the handy “Cloning” feature. This requires a user-constructed C loning cable which connects the DATA jacks on the two transceivers, as shown below .

To clone from one transceiver to another, use the following procedure:

1. Insert the Clone Cable into the DATA jack of each transceiver.

2. Turn both transceivers off, then press and hold in the “left” and “right” [V/M] keys

on each radio while turning the p ow er on again.

3. Rotate the “right” DIAL knob on each radio to select (CLONE START ), then press

the [SET] key. Disappear the display for a moment, then “CLONE” notation will appear on the display.
