 <note important> ​ * **check the receiver position with ''​rxp''​** Should be -256, +248, +18 (x,y,z). The values may be off by 2-3 mm which is the measurement noise. The 26m live page will have the receiver listed (left side)as "​S/​X"​ if all is well.</​note>​ <note important> ​ * **check the receiver position with ''​rxp''​** Should be -256, +248, +18 (x,y,z).

-  * If the cryomon or rxmon fs commands don't work (e.g. "rx - device timed out on response"​) try reset the TTY Distributor panel on the old MarkIV s/x rack, with the reset switch. The serial comms from the receiver to Hobart ​fs computer are patched through the TTY Distributor.+  ​* **Troubleshoot** If the cryomon or rxmon fs commands don't work (e.g. "rx - device timed out on response"​) try reset the TTY Distributor panel on the old MarkIV s/x rack, with the reset switch. The serial comms from the receiver to hobart ​fs computer are patched through the TTY Distributor. Otherwise a power cycle of the receiver may be required.
     * **Cryogenics:​ Vacuum pressure less than 3.5**. The Vacuum pressure in the S/X dewar should be below this value (measured in microns of Mercury). If it increases above this value, it indicates a leak. Let Brett know. e.g. this readout indicates a vacuum pressure of 1.227 <​code>​2014.126.09:​00:​46.53/​rx/​17(pres),​on,​a,​on,​on,​on,​off,​locked,​1.227</​code>​     * **Cryogenics:​ Vacuum pressure less than 3.5**.

     * **Cryogenics:​ 70K stage temperature below 65K**. The S/X dewar contains a 20K and a 70K stage. If the 70K stage temperature exceeds about 65K, this indicates the receiver is warming up and needs attention. Contact Brett. e.g. this readout indicates a 70K stage temperature of 167K (not good!) <​code>​2014.126.09:​01:​49.97/​rx/​1F(70k),​on,​a,​on,​on,​on,​off,​locked,​167.0</​code>​     * **Cryogenics:​ 70K stage temperature below 65K**.
