2303 Stabilock

Regular testing of TETRA phones ensures safe and reliable communication

In critical situations, users in the public safety and security sector fully rely on their communication devices. To help organisations such as police, fire brigades and paramedics provide maximum safety and reliability to their users, Willtek designed the 2303 Stabilock. It is the first TETRA mobile station tester which is specifically made for testing TETRA radios in a service environment. Service managers can now use the affordable instrument to ensure that the radios are fully operational; this is particularly important for the police, fire brigades and paramedics where lives may depend on proper communication tools! The 2303 Stabilock delivers precise results the fast way. No matter if Trunked Mode or Direct Mode (optional), 400 or 800 MHz band: After setting up network parameters and frequency range the tester is ready for operation. The high contrast 6.5” TFT colour display is split into four sections for clear reading of test results in numeric or graphic format. All settings and commands are accessible via six softkeys or with one-hand operation using the turn-and-push dial. Reducing TETRA complexity to what is really needed in service – with this operational concept, users can operate the instrument easily with a few key presses on the Stabilock’s high-quality click-type keyboard. Alternatively, a standard USB mouse provides access to all screen elements as on a PC.
