The SOLT SB6-2XWH-F (KT Automation reference KTI040120SLTB62X) wireless transmitter streamlines deployment across critical medical environments by utilizing a cable-free 400 MHz radio frequency link to nurse stations. Complete installation requires positioning the main transmitter module, deploying the tethered foot switch, inserting internal coin cells, and verifying RF signal reception with the facility's central receiver hardware.
Transmitter Wall Mounting and Positioning
The main transmitter unit features a slim Snow White enclosure measuring 100 mm (W) x 60 mm (L) x 16.5 mm (H) with a total weight of approximately 46 g. Mount the transmitter enclosure securely to a clean, vertical wall surface at a height that permits direct, clear visibility of the high-brightness LED indicator and allows clinical personnel easy access to the integrated front-facing Cancel button.
Because the unit incorporates a built-in internal helical antenna providing 360-degree omnidirectional RF propagation, mounting orientation does not degrade signal coverage. However, avoid mounting the transmitter directly onto solid sheet metal or inside metallic enclosures, which can attenuate the low-power 400 MHz Frequency Shift Keying (FSK) transmission.
Foot-Step Switch Placement and Cable Management
The transmitter is permanently wired to a heavy-duty foot-step switch via a 1.4 m tethered cable. Proper positioning of this external actuator depends on the clinical environment:
- Operating Theatres and Surgical Suites (OT/OR): Position the foot actuator within immediate reach of surgical staff to allow completely hands-free call initiation without breaching sterile fields.
- Accessible Restrooms and Washrooms: Mount the main transmitter on the wall and position the foot switch flat on the floor level to ensure patients who slip or fall can actuate an emergency call from ground level.
- Patient Bedside and Nursing Homes: Place the actuator on the floor alongside the bed frame for patients with upper-limb mobility limitations.
Ensure the 1.4 m cable is routed cleanly along baseboards or wall perimeters to eliminate snagging risks, physical entanglement, and mechanical crushing from medical cart wheels or bed casters.
Power Supply Setup
The transmitter circuitry is powered by CR2032 coin cell batteries (they are not included). Open the transmitter casing, seat two CR2032 coin cell batteries (they are not included) observing correct terminal polarity, and reassemble the casing securely. The low-power FSK transmission circuit yields an operational battery life of 1 to 3 years depending on daily actuation cycles.
System Pairing and RF Range Verification
Once powered, calibrate the transmitter to the facility's receiving infrastructure:
- Trigger the foot-step switch and observe the high-brightness LED on the transmitter to verify transmission.
- Register the transmitter ID code into the designated SOLT receiver display panel (compatible with SM3-32PN, SM3-33PC, or SM3-61PC).
- If deployed, verify registration across SOLT SP5, SP7, or SP9 mobile staff pagers, SL series corridor door lights, and SR5-MPR monitoring receivers running central logging software.
- Conduct walk-through transmission tests across the ward. In large facilities with dense reinforced concrete partitions, install SOLT SR5-BPR signal repeaters to bridge any transmission gaps.
