BATTERY PACKS I Installing batteries in the battery case When using a battery case attached to the transceiver, install 8 AA(R6) size Ni-Cd or alkaline batteries as illustrated below. ➀ Remove the bat- tery case from the transceiver. ➁ Install 8 × R6(AA) size Ni-Cd or alka- line batteries.
I Power ON Rotate [PWR/VOL] clockwise to turn power ON. D Toggling frequency/channel indication mode Channel indication mode is used to simplify operation. In this mode only pre-programmed memory channel numbers are displayed and functions are limited ([PWR/VOL], [ ], [H/L] and [SC] are functional). To toggle between the indication modes: While pushing [Z] + [0], rotate [PWR/VOL] to turn power ON.
BASIC OPERATION I Dial select function Use the dial select function to adjust the tuning behaviour or the [Y]/[Z] keys—use 1 MHz tuning when you want to change the frequency in large increments; use the selected tuning step when you want to change the frequency in smaller increments.
✔ Convenient Monitor function: Push and hold [ ] to listen to weak sig- nals that do not open the squelch; or push [ itor a signal without having to continuously hold [ Squelch control: The transceiver employs a noise pulse count system and therefore, squelch is adjusted automatically when “AUto”...
BASIC OPERATION I Notes for “Set mode” The following items can be set from VFO mode. Set mode items: Tuning steps (p. 14) Duplex setting (p. 15) Repeater tones (p. 16) Offset frequency (p. 16) Subaudible tones (p. 16) Call channel (p.
I General When using a repeater, the transmit frequency is shifted from the receive frequency by the offset frequency. It is convenient to program repeater information into memory channels (p. 19). ➀ Set the receive frequency (repeater output frequency). ➁ Push [DUP] one or more times to select –DUP or DUP.
REPEATER OPERATION I Subaudible tones Some repeaters require subaudible tones to be accessed. Subaudible tones are superimposed over your normal signal and must be set in advance. ➀ Push [ V] for 1 sec. to enter set mode. ➁ Push [t] one or more times until “RP”...
I Auto repeater USING function (USA version only) The USA version automatically activates the repeater settings (duplex, ON/OFF, duplex direction, tone encoder ON/OFF) when the operating frequency falls within or outside of the general repeater output frequency range. The offset and re- peater tone frequencies are not changed by the auto repeater function, reset these frequencies, if necessary.
REPEATER OPERATION WEATHER CHANNELS (USA version only) There are 10 weather channels for monitor- ing weather channels from the NOAA (Na- tional Oceanographic and Atmospheric Administration) broadcasts. NOTE: The weather channel frequencies are out of the guaranteed frequency range (see p. 38). Intermittent re- ception and/or poor signal quality may occur depending on conditions.
I General The transceiver has 40 memory channels (plus 1 pair of scan edge channels and 1 call channel) for storage of often-used frequencies. In addition, the USA version has 10 marine weather channels (however, these are not programmable). D Memory/call channel contents The following information can be programmed into mem- ory/call channels: •...
MEMORY/CALL PROGRAMMING I Programming the call channel ➀ Push [ (CALL)] to select call channel mode. • “C” appears. ➁ Push [ (CALL)] for 1 sec. to enter set mode. ➂ Push [t] one or more times until “FR” appears. ➃...
I Memory editing Memory (call) channel contents can be moved to VFO or to another memory. D Memory/call ➾ VFO ➀ Select the memory (call) channel to be transferred: ➥ Push [ V] ([ (CALL)]) to select memory (call) mode. ➥...
DTMF MEMORY I Programming a DTMF code The transceiver has 5 DTMF memory channels (d1 to d5) for storage of often-used DTMF codes of up to 32 digits. ➀ Push [ (DTMF)] to enter DTMF memory. • One of “d1” to “d5” appears. ➁...
I DTMF USING transmission speed When slow DTMF transmission speeds are required (as for some repeaters), the transceiver’s rate of DTMF transmission can be adjusted. ➀ While pushing [8] + [0], turn power on to enter initial set mode. ➁ Push [t] one or more times until “dt”...
Band condition determines what ac- edge tion the transceiver takes. The IC-T2H has 2 scan resume conditions available as illus- trated at right. Use initial set mode to select the one which best suits your needs.
I Programmed scan Programmed scan repeatedly scans between two user-pro- grammed frequencies (memory channels “PA” and “Pb”). This scan is useful for checking for signals within a specific fre- quency range such as repeater output frequencies, etc. ➀ Push [ V] to select VFO mode, if necessary.
SUBAUDIBLE TONE OPERATION I Tone squelch D Operation The tone squelch opens only when receiving a signal con- taining a matching subaudible tone. You can silently wait for calls from group members using the same tone. ➀ Set the operating frequency. ➁...
I Tone scan The transceiver can detect the subaudible tone frequency in a received signal. By monitoring a signal, such as that being transmitted on a repeater input frequency, you can determine the tone frequency required to access the repeater. ➀...
OTHER FUNCTIONS I Initial set mode Initial set mode is accessed at power on and allows you to set seldom-changed settings. In this way you can “customize” transceiver operations to suit your preferences and operating style. D Entering initial set mode ➀...
D Auto power OFF This item allows you to set a time at which the transceiver will automati- cally turn OFF. The power OFF time can be set to 20, 40, 60 min. or turned off. D LCD backlighting When set to AUTO, display backlight- ing automatically turns on when a key is pushed;...
OTHER FUNCTIONS D Scan resume condition D Active memory channels This item allows you to adjust the number of active memory channels. Selectable values are 10, 20, 30 or I Resetting the CPU (see p. 24) Reset the CPU before operating the transceiver for the first time, or when the internal CPU malfunctions.
I Key customize mode The functions of the [SQL], [SC], [DUP], [H/L], [ T] and [ L] keys on the IC-T2H can be customized to suit your operating needs. ➀ While pushing [#] + [0], turn power on to enter key customize mode.
