This is exactly what I needed This was a hard one to find and I had already downloaded several for other Panasonic radios but none matched my radio.
Although my radio is the LBE model the LBS is the same.
A very good quality manual with every thing you should get in it

ADJUSTMENT
X25 Circuit Adjustment Specification (M : For the Other Markets) Item
1. Video detection co il adjustment L303
Adjustment method/Adjustment value
1. Turn VR301 [RF-AGC] fully to the right. 2. Apply DC2.0V to TP [IF AGC] (IC300 pin36). 3. Feed fo=38.0MHz, Mod=1kHz, AM60%, Level=100dBµ into TP [IF] (A100 pin8). 4. Observe the TP [VIDEO] (IC300 pin8) waveform on an oscilloscope and adjust L303 for maximum level.
Conditions
No ANT signal If the waveform is clipped, slightly increase the DC voltage. AC range
Maximum
2. Audio detection coil adjustment L300
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed fo=31.5MHz, No Modulation, Level=94dBµ into TP [IF] (A100 pin8). 3. Connect a voltmeter to TP [SIF] (both ends of R314) and adjust L300 for 0V ± 0.01V.
No ANT signal
3. S-METER adjustment VR300 4. RF AGC adjustment VR301
1. Turn VR301 [RF-AGC] fully to the right. 2. Feed a 30dBµ CHINA 9CH color bar RF signal into the ANT input terminal. 3. Audio (P/S ratio -6dB) no modulation. 4. Connect a voltmeter to CN300 and adjust VR300 [SMET] so it reads 3.5V ± 0.05V. 5. Set the RF signal to 70dBµ and adjust VR301 [RF-AGC] so that the voltmeter connected to CN300 reads 4.8V ± 0.05V.
Postpone adjusting VR301 to prevent AGC having effect at 30dBµ. Ensure the RF AGC adjustment is performed after the S-METER adjustment. No ANT signal Test mode
5. Diversity free run frequency adjustment VR400
1. Connect a frequency counter to CN400. 2. Using the remote control unit TV/NAVI button, switch to adjustment mode. 3. Adjust VR400 [15kHz] so as to obtain 15625 ± 100Hz.
