Manual OFF for hopping ARQ and ALE mode indexes requires selection of CLEAR from operations.
Function switch must be on CT to select TEK-01 (addresses from 01 to 99).

Establishing Link on 3G Mode

Keep the function switch on PT or CT.
Activate 3G mode via pushbutton number 3 (Mod).
Press call button (1) to display options: Synchronized Request, Best, Automatic, Manual.
Selecting Best or Automatic leads to further options: Net and Station for linking.
Link Quality Analysis (LQA) conducted before manual operations to ensure channel reliability.
Maximum link termination set at 999 seconds; if inactive, link will terminate.

Establishing Link on ALE Mode

Similar to 3G mode, keep the function switch on PT or CT.
Enter ALE mode using button 3; options displayed are Automatic and Manual.
In Automatic mode, options include All, Any, Individual, Group, and Net to establish a link.
Individual option allows selection from a station list after linking analysis.
Manual operation requires channels with good LQA scores to be identified before linking.

Preparing Preset Channel

Set function switch to PT or CT and press button 3 (Mod) to choose FIX, HOP, ALE, or 3G.
Use Program button to initiate operations: SCHED, ACCESS, MODE, CONFIG.
Navigate to PRESET, followed by CHANNEL selection to input specific channel details.
Complete configuration includes setting frequencies, modulation, transmission power limits, and whether to enable hail transmission.

Preparing Preset System

Similar step to preset channel but emphasizes creating and naming the preset system.
Select data modem and encryption type, along with specifying vocational options before finalizing the system.

SMS Sending in 3G Mode

Switch to PT or CT and select 3G mode using button 3 (Mod).
Access MSG to input a new message, choosing to send to NET or STATION.

AMD Sending in ALE Mode

Follow the same initial steps as SMS sending but choose ALE mode.
Use programming options to edit and send messages, allowing for manual or automatic transmission modes.

Short Message Service (SMS) and Last Ditch Voice (LDV) Reading

Enter interface for reading messages from the display unit to check for any received messages.

Checking Radio Name Station-wise

Access station parameters to check details including frequency modulation, transmission power, and squelch level.

Operating on Hopping Mode

Activate hopping mode using button 3 while ensuring the net is displayed.
Call button leads to SYNC SIG/SYNC REQUEST operations; wait for responses to establish hopping communication.

Hailing Operation

Initiate hail from a fixed mode channel to allow new stations to join the hopping network.

Changing Antenna Position

Change settings via configuration options to match the antenna type (e.g., RF-5382, 50 OHM).

Differences Between ALE and 3G Modes

3G allows linking at lower SNRs compared to ALE, with distinct channel ranges.
More data can be transferred in 3G, which lacks manual programming compared to ALE.
3G provides SMS capabilities while ALE allows AMD transmissions.
3G linking is faster; LDVs are exclusive to 3G.

Battery Checking Procedure

Activate the radio and use mode button (3) to access battery options through TEST menu, focusing on voltage and status readings.

Procedure for Sending LDV
