Generally speaking good copy; a few pages too hard contrast...
Good service and communication.

I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.

Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.
Model 598T User Guide
GENERAL DESCRIPTION
The 598T is a handheld, amplified, noise-canceling communications microphone that is FAA Certified for aircraft application (TSOC58a). In addition to its extremely clear transmission, even in noisy environments, the 598T has very low sensitivity to hum pickup and low susceptibility to radio frequency interference. The 598T is ergonomically designed and fits naturally in the hand. Its high-impact ARMO-DUR® case is strong, lightweight, and comfortable to the touch in hot or cold environments. A five-conductor MODULINK® cable (sold separately) connects the microphone to the PJ-068 plug on most aircraft radios. This cable can be instantly changed or replaced without soldering. A miniature screwdriver is supplied for unlocking and removing the cable. The microphone is powered directly from the microphone input of the transmitter, allowing the 598T to be installed and operated with most modern aircraft radios without equipment modification. Output levels are factory preset to meet TSO-C58a requirements. Only an FAA Approved Service Facility or Shure Incorporated should make adjustments.
APPLICATIONS
Voice communication, including aerospace.
PART OF A COMPLETE LINE
The 598T is part of a full line of mobile microphones, circuitry products and related accessories. For a complete listing, contact your Shure Representative or visit www.shure.com.
SET-UP
Mounting
A hang-up loop comes affixed to the microphone. Heavy-duty mounting brackets for attachment to radio equipment or other surfaces are available as an accessory (Shure RK6MB).
Cable
To attach the cable to the 598T, insert the modular telephonetype plug in the microphone jack until it locks. To remove the cable, insert the supplied miniature screwdriver in case hole just above the cable jack (see Figure 1) to unlock the plug and withdraw the plug from the jack. The MODULINK® cables are wired at the microphone connector as shown in Figure 4. See the microphone connector wiring table (Table 1).
